Claim that for the population of statistic:

The mean score is 74, using alternative hypothesis that the mean score is different from 74. Sample statistics include n=21,, x=76,x¯=76, and s=11. Use a significance level of α=0.05.

Test Statistic:

Positive Critical Value:

Negative Critical Value:

Conclusion:

A. There is not sufficient evidence to reject the claim that the mean score is equal to 74

or

B. There is sufficient evidence to reject the claim that the mean score is equal to 74

You wish to test the claim that the average IQ score is less than 100 at the .005 significance level. You determine the hypotheses are: Ho: μ=100 H1:μ<100 You take a simple random sample of 76 individuals and find the mean IQ score is 95.5, with a standard deviation of 15.1. Let's consider testing this hypothesis two ways: once with assuming the population standard deviation is not known and once with assuming that it is known. Round to three decimal...
