In a study of the effectiveness of a certain diet, 100 subjects went on the diet for a period of six months. The sample mean weight loss was 0.5 pound, with a sample standard deviation of 4 pounds.Can you conclude that the diet produces a mean weight loss that is greater than 0? Use the α = 0.05 level of significance.Perform the hypothesis test, make sure you follow each step and show all your work.

In a recent medical study, 81 subjects were placed on a low-fat
diet. After 12 months, their sample mean weight loss was 2.2
kilograms, with a sample standard deviation of 6.1 kilograms.
Construct an appropriate test to conclude if the mean weight loss
is greater than 0 at an α = 0.01 significance level.

Here we study the effectiveness of two dieting methods. Method 1
is a diet high in protein, fiber, and fat but low in carbohydrates.
Method 2 is a diet low in fat but high in fiber and carbohydrates.
After one year, a sample of participants from each diet method were
checked for the amount of weight lost. The 99% confidence intervals
for the mean weight loss of each plan are given below.

Q.1. ) Low-carbohydrate diet A study plans to have a sample of
obese adults follow a proposed low-carbohydrate diet for three
months. The diet imposes limited eating of starches (such as bread
and pasta) and sweets, but otherwise no limit on calorie intake.
Consider the hypothesis, The population mean of the values of
weight change (= weight at start of study - weight at end of study)
is a positive number.
