The last digit of the heights of 58 statistics students were obtained as part of an Choose the correct histogram below. experiment conducted for a class. Use the following frequency distribution to construct a histogram. O A' 16 What can be concluded from the distribution of the digits? Specically, do the heights appear to be reported or actually measured? H 00123456789 Digit Frequency B.

The heights occur with roughly the same frequency. 0 B. The data appears to be measured. Certain heights occur a disproportionate number of times. 0 c. The data appears to be reported. The heights occur with roughly the same frequency. 0 D. The data appears to be reported. Certain heights occur a disproportionate number of times. The accompanying data set lists the F-scale intensies of recent tornadoes in the United States. Construct a frequency distribution. Do the intensities appear to have a normal distribution? Assume that the intensities are quantitative. E Click the icon to view the F-scale intensities. F-scale intensities Complete the frequency distribution. F-Scale Intensity Frequency 0 20 1 1 4 2 2 3 2 4 El (Type whole numbers.) Do the intensities appear to have a normal distribution? (Q A. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric. O B. No, because while the distribution is approximately symmetric, the frequencies start at a maximum and become low. 0 C. No, because the frequencies start at a maximum and become low, and because the distribution is not symmetric. O D. No, because while the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, the distribution is not symmetric. The table lists weights (pounds) and highway mileage amounts (mpg) for seven automobiles. Use the sample data to construct a scatterplot. Use the first variable for the x-axis. Based on the scatterplot, what do you conclude about a linear correlation? Weight (lb) 2960 3185 3565 3965 3985 2440 3265 Highway (mpg) 34 32 29 25 24 38 30 Which scatterplot below shows the data?

O A. Yes, as the weight increases the highway mileage decreases. O B. No, there appears to be no relationship. O C. Yes, as the weight increases the highway mileage increases. O D. No, there appears to be a relationship, but it is not linear.The frequency distribution below represents frequencies of actual low temperatures recorded during the course of a 31-day month. Use the frequency distribution to construct a histogram. Do the data appear to have a distribution that is approximately normal?
