The nutritionist wants to determine if the satisfaction levels (measured from 1-10, 10 being the highest) of the clients on the high-protein diet are the same among the three types of meat (fish, pork, chicken). Which between a parametric test or a non-parametric test will you suggest to analyze the given data?

Question

The nutritionist wants to determine if the satisfaction levels (measured from 1-10, 10 being the highest) of the clients on the high-protein diet are the same among the three types of meat (fish, pork, chicken). Which between a parametric test or a non-parametric test will you suggest to analyze the given data?

The nutritionist also wants to determine if there is a difference in the average weight loss between male
and female clients. Men tend to lose weight faster due to their higher percentage of lean muscle tissue
and higher metabolic rate. To answer this, you recommended to use a parametric test t-test which
requires the data of each group be normally distributed. Using R Commander, the following results for the
test of the assumptions were generated.
R COMMANDER OUTPUT
sex = female
Shapiro-Wilk normality test
weightloss
data:
W = 0.94514, p-value = 0.2748
----
sex - male
Shapiro-Wilk normality test
data: weightloss
W - 0.97646, p-value
- 0.8227
