Question 1 1 pts Twelve teachers attended a seminar on mathematical problem solving. Their attitudes were measured before and after the seminar. A positive number change attitude indicates that a teacher's attitude toward math became more positive. The twelve change scores are as follows: 3, 8, -1, 2, 0, 5, -3, 1, -1, 6, 5, -2 You will need to open a blank StatCrunch worksheet and then put the numbers vertically into a column, one number in each cell. There are a few videos in this module that go over StatCrunch that may help! The mean is: [Select] (Round to two decimal places). The sample standard deviation is: [Select] (Round to two decimal places). The first quartile is: [Select] The median is: [Select] The third quartile is: [Select] Question 2 1 pts The statistics below describe the data collected that represents the number of calories in a single serving of cereal for 15 types of cereals. Note that (or mu) is the letter used for mean and (sigma) is the term used for standard deviation f = 182 Median = 186 = 15 Q1 = 172 Q3 = 197 n-18 A sample of 30 cereal boxes is taken. What is the best prediction for the number of boxes that contain more than 186 calories? That means, out of the 30 boxes in your sample, how many would you expect to be more than 186 calories? [Select] 25% of all cereals have more than how many calories per serving? [Select] 25% of all cereals have fewer than how many calories per serving? [Select] What percent of all servings of cereal have between 172 and 197 calories? [Select] percent. Question 3 1 pts The statistics below show the full-time equivalent student (FTES) count for the history of Lake Tahoe Community College. Note that is the letter used for mean and is the term used for standard deviation Mean, = 1000 FTES Median = 1014 FTES Standard Deviation, = 474 FTES Q1=528.5 FTES = Q3 1447.5 FTES n = 29 years A sample of 8 years is taken. What is the best prediction for the numbers of these years that have fewer than 1014 FTES? That is, out the 8 years you have in your sample, how many would you expect to be fewer than 1014 FTES? [Select] 25% of all years had at least how many FTES? [Select] 25% of all years had at most how many FTES? [Select] What percent of all the years had between 1014 and 1447.5 FTES? [Select] percent. Question 4 1 pts The following shows the results of a survey asking women how many pairs of shoes they own : 2, 4, 4, 5, 7, 8, 8, 9,12,15,17,28 Use statistical software such as StatCrunch. You will need to open a blank StatCrunch worksheet and then put the numbers vertically into a column, one number in each cell. There are a few videos in this module that go over StatCrunch that may help! The mean is: [Select] (Round to two decimal places). The sample standard deviation is: [Select] (Round to two decimal places). The first quartile is: [Select] The median is: [Select] The third quartile is: [Select] This is a quiz and you only get 1 attempt! Remember, you don't have to complete it once you start where you can leave and come back later to finish it before the due date. Some helpful hints: For questions that ask for the mean, median, standard deviation (s), etc. you should be using StatCrunch to find them!!!! , is the MEAN , is the STANDARD DEVIATION
