In a test of a particular weight loss program, weights of 40 subjects are recorded before and ( point) after the program. The before-and-after weights result in a correlation coefficient of 0.876. Assuming a 0.05 significance level, find the critical values. Is there sufficient evidence to support the claim of a linear correlation between before-and-after weights? a. Critical values 0.312; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights. b. Critical values 312; there is not sufficient evidence to support a claim of a linear correlation between before-and-after weights. c. Critical values +0.402; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights. d. Critical values0.402, there is not sufficient evidence to support a claim of a linear correlation between before-and-after weights.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
