BE SURE TO USE A TI 84 CALCULATOR AND SHOW ALL STEPS/ COMMANDS USED.

Conduct a hypothesis test showing all of your steps.

Females under the age of 51 years old are supposed to get, on average, 18 mg of iron daily. In a random
sample of 44 women, their daily mean intake was 16.77 mg of iron with a standard deviation of 3.02 mg.
An agency claims that women get less than the recommended daily iron intake. Test this claim with a 4%
level of significance.

a) State the hypotheses and label the claim.

b) Is it left-tailed, right-tailed, or two-tailed?

c) What are the critical values? Draw a picture.

d) What is the P-value and/or test-statistics?

e) Give two reasons for your decision to reject/not reject H0 based on: A. Test statistic compared to critical value(s) B. P-value compared to α. State the conclusion, relating it back to the original claim.
