The changes in weight during three months for six people on a diet were 10,12, 14, 16, 17, and −2 pounds. Use the sign test to find and interpret the P-value for testing that the probability that the weight difference is positive equals 0.50 against the alternative hypothesis that it is greater than 0.50.

1) Identify the correct null and alternative hypotheses.

I know that the correct answer for this part is:

H0 : p = 0.50

Ha : p > 0.50

2) P-value = ?

But I have no idea how to calculate the p-value here, can anyone help me?

Thanks in advance.

A study of 50 people who were not on a diet showed that they consumed an average of 2200 calories in a day, with a standard deviation of 400 calories per day. For 40 people who were on a diet, they consumed an average of 2100 calories per day, with a standard deviation of 250 calories per day. Assume both populations are normally distributed. a) Test the claim that people on a diet consume fewer calories. b) Test the claim...
