question 8

Listed below are the ages of 11 players randomly selected from the roster of a championship sports team. Find the (a) mean, (b) median, (c) mode, and (d) midrange and then (e) determine how the resulting statistics are fundamentally different from those calculated from the jersey numbers of the same 11 players. 40 23 28 32 33 27 25 26 26 25 28 Click the icon to view jersey numbers data and statistics. a. Find the mean. The mean age is years. (Type an integer or a decimal rounded to one decimal place as needed.) b. Find the median. The median age is | years. Nextisted below are the ages of 11 players randomly selected from the roster of a championship sports team. Find the (a) mean, (b) median, (c) mode, and d) midrange and then (e) determine how the resulting statistics are fundamentally different from those calculated from the jersey numbers of the same 1 players. 40 23 28 32 33 27 25 26 26 25 28 Click the icon to view jersey numbers data and statistics. The midrange is years. (Type an integer or a decimal rounded to one decimal place as needed.) e. How are the resulting statistics fundamentally different from those calculated from the jersey numbers of the same 11 players? The jersey numbers are data at the level of measurement, but the ages are data at the level of measurement, so statistics are meaningful. NextListed below are the measured radiation emissions (in W/kg) corresponding to cell phones: A, B, C, D, E, F, G, H, I, J, and K respectively. The media K often present reports about the dangers of cell phone radiation as a cause of cancer. Cell phone radiation must be 1.6 W/kg or less. Find the a. mean, b. median, c. midrange, and d. mode for the data. Also complete part e. 1.06 1.51 0.41 0.97 0.52 0.49 1.04 1.49 0.39 1.45 1.33 a. Find the mean. The mean is (Round to three decimal places as needed.) b. Find the median. The median is (Type an integer or a decimal.) NextListed below are the measured radiation emissions (in W/kg) corresponding to cell phones: A, B, C, D, E, F, G, H, I, J, and K respectively. The media often present reports about the dangers of cell phone radiation as a cause of cancer. Cell phone radiation must be 1.6 W/kg or less. Find the a. mean, b. median, c. midrange, and d. mode for the data. Also complete part e. 1.06 1.51 0.41 0.97 0.52 0.49 1.04 1.49 0.39 1.45 1.33 e. If you are planning to purchase a cell phone, are any of the measures of center the most important statistic? Is there another statistic that is most relevant? If so, which one? O A. The mean of the data set is the most important statistic because cell phones that have values close to it have the safest emissions. O B. The maximum data value is the most relevant statistic, because it is closest to the limit of 1.6W/kg and that cell phone should be avoided. O C. The minimum data value is the most relevant statistic, because it is closest to the limit of 1.6W/kg and that cell phone should be purchased. O D. The midpoint of the data set is the most important statistic because cell phones that have values close to it have the safest emissions. NextThe brain volumes (cm") of 20 brains have a mean of 1051.7 cm and a standard deviation of 124.1 cm. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1269.9 cm be significantly high? Is 1269.9 cm significantly high? A. Yes, because it is between the limits separating values. O B. No, because it is above the upper limit separating value. O C. Yes, because it is above the upper limit separating value. O D. Yes, because it is below the lower limit separating value. O E. No, because it is below the lower limit separating value. O F. No, because it is between the limits separating values. NextListed below are prices in dollars for one night at different hotels in a certain region. Find the range, variance, and standard deviation for the given sample data. Include appropriate units in the results. How useful are the measures of variation for someone searching for a room? 146 143 137 132 170 115 269 163 The range of the sample data is (Round to one decimal place as needed.) The standard deviation of the sample data is (Round to one decimal place as needed.) The variance of the sample data is (Round to one decimal place as needed.) NextThe brain volumes (cm) of 20 brains have a mean of 1051.7 cm and a standard deviation of 124.1 cm. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1269.9 cm be significantly high? Significantly low values are cm or lower. (Type an integer or a decimal. Do not round.) Significantly high values are cm or higher. (Type an integer or a decimal. Do not round.) Is 1269.9 cm significantly high? O A. Yes, because it is between the limits separating values. NextListed below are prices in dollars for one night at different hotels in a certain region. Find the range, variance, and standard deviation for the given sample data. Include appropriate units in the results. How useful are the measures of variation for someone searching for a room? 146 143 137 132 170 115 269 163 How useful are the measures of variation for someone searching for a room? O A. The measures of variation are not very useful because when searching for a room, low prices, location, and good accommodations are more important than the amount of variation in the area. O B. The measures of variation are very useful because a person does not want to buy a room where the variation is too high. O C. The measures of variation are not very useful because the values are nominal data that do not measure or count anything, so the resulting statistics are meaningless. O D. The measures of variation are very useful because a person does not want to buy a room where the variation is too low. NextListed below are the ages of 11 players randomly selected from the roster of a championship sports team. Find the (a) mean, (b) median, (c) mode, and (d) midrange and then (e) determine how the resulting statistics are fundamentally different from those calculated from the jersey numbers of the same 11 players. 40 23 28 32 33 27 25 26 26 25 28 Click the icon to view jersey numbers data and statistics. c. Find the mode. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The mode(s) is(are) year(s). (Type an integer or a decimal. Do not round. Use a comma to separate answers as needed.) O B. There is no mode.
