Statistics
To determine the effects, researchers measured the LDL levels of 36 randomly selected men and 41 randomly selected women before and after spending 6-weeks on a plant-based diet. The researchers then subtracted the two values corresponding to each individual and found the mean reduction for each group. For men, the mean reduction in LDL was 13.3 mg/dl with a standard deviation of 1.3 mg/dl. For women, the mean reduction in LDL was 15.4 mg/dl with a standard deviation of 1.9 mg/dl. Both the scatterplots for the mean LDL reduction in men and women resemble a normal distribution. We will test Ho : H = 42 Vs. Ha : H1 + H2. Compute the test statistic of interest (women- men), accurate to three digits beyond the decimal point. Answer: | What is the null distribution of the test statistic? Select one: a. AT distribution with 35 degrees of freedom. O b. AT distribution with 76 degrees of freedom. O . AT distribution with 375 degrees of freedom. O d. AT distribution with 40 degrees of freedom. O e. AZ distribution.

Question
To determine the effects, researchers measured the LDL levels of 36 randomly selected men and 41 randomly selected women before and after spending 6-weeks on a plant-based diet. The researchers then subtracted the two values corresponding to each individual and found the mean reduction for each group. For men, the mean reduction in LDL was 13.3 mg/dl with a standard deviation of 1.3 mg/dl. For women, the mean reduction in LDL was 15.4 mg/dl with a standard deviation of 1.9 mg/dl. Both the scatterplots for the mean LDL reduction in men and women resemble a normal distribution. We will test Ho : Hi = H2 VS. Ha : Hi 7 H2. Compute the test statistic of interest (women- men), accurate to three digits beyond the decimal point. Answer: What is the null distribution of the test statistic? Select one: a. AT distribution with 35 degrees of freedom. O b. AT distribution with 76 degrees of freedom. O c. AT distribution with 37.5 degrees of freedom. O d. AT distribution with 40 degrees of freedom. O e.
