Question

For the following discussion, your answer should be a complete test of hypothesis. Please notice that the sample size is small. For your answer, you should have the following.

1. State your null and alternative hypothesis

2. Calculate the standardized test statistic

3. Find either the pvalue and compare it to the level of significance (alpha). OR. Find the critical value(s) and define the rejection region(s) and then compare the standardized test statistic.

4. State your conclusion in the context of the claim.

The problem is below.

Hello Math 117, SBCC charges $2.00 for a Cliff Bar on campus. I claim that the mean cost of a Cliff Bar is less expensive off campus than on campus at SBCC. To help support my claim, I collect a sample off campus of size 10 and find that the mean cost of a Cliff Bar is $1.58 with a standard deviation of $0.17. Can you support my claim that the mean cost of a Cliff Bar is less expensive off campus? Please show all steps mentioned above for the Test of Hypothesis. You may use a level of significance of 0.05 (alpha=5%).

Answer 1

Since p <a, We reject Hoiles $2.00 Hence there is enor lough evidence to conclude that mean cost of a cliff Bar is less expensive off campus,
