You will perform a Two Sample Hypothesis Test for Means. For the Hypothesis Tests, make sure to report the following steps:

Identify the null hypothesis, Ho, and the alternative hypothesis, Ha.

Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.

Find the critical value(s) and identify the rejection region(s).

Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis.

Interpret the decision in the context of the original claim.

Question: A science teacher claims that the mean scores on a science assessment test for fourth grade boys and girls are equal. The mean score for 63 randomly selected boys is 151 with a standard deviation of 36, and the mean score for 65 randomly selected girls is 149 with a standard deviation of 34. At α = 0.10, can you reject the teacher’s claim? Assume the populations are normally distributed and the population variances are equal.

A hypothesis will test that two population means are equal. A sample of 10 with a standard deviation of 3 is selected from the first population and a sample of 15 with a standard deviation of 8 from the second population. The standard deviations are not equal. Testing the claim at the 0.01 level, what is the critical value? Assume unequal standard deviations. Please explain and show your work. Thank you!

For all hypothesis tests, be sure to include information for all 7 steps. For any two-sample or paired t-tests that you perform, in Step 6, show the decision rule based on BOTH the critical value and the p-value. Use the online app for the t-distribution to compute your p-values. The Bayley Scales of Infant Development yield scores on two indices – the Psychomotor Development Index (PDI) and the Mental Development Index (MDI) – that can be used to assess a...
