In marketing children’s products, it is extremely important to produce television commercials that hold the attention of the children who view them. A psychologist hired by a marketing research firm wants to determine whether differences in attention span exist among advertisements for different types of products.

The results are shown in the accompanying table:   Type of Product Advertised Toys/Games Food/Candy Children’s Clothing 42 55 30 45 58 35 48 52 42 40 60 32 50 57 38 b). What type of error is possible and describe this error in terms of the problem.

A sample of blood pressure measurements is taken from a data set and those values​ (mm Hg) are listed below. The values are matched so that subjects each have systolic and diastolic measurements. Find the mean and median for each of the two samples and then compare the two sets of results. Are the measures of center the best statistics to use with these​ data? What else might be​ better?   ​Systolic: 97 96 134 112 154 116 156 99 153 117     ​Diastolic: 63 55 87 73 76 88 85 79 69 62     Find the means.   The mean for systolic is nothing mm Hg and the mean for diastolic is nothing mm Hg. ​(Type integers or decimals rounded to one decimal place as​ needed.) Find the medians.   The median for systolic is nothing mm Hg and the median for diastolic is nothing mm Hg. ​(Type integers or decimals rounded to one decimal place as​ needed.) Compare the results. Choose the correct answer below.     A. The median is lower for the…
