Do political science classes require the same amount of writing as history classes? The 59 randomly selected political science classes assigned an average of 15.1 pages of essay writing for the course. The standard deviation for these 59 classes was 4.6 pages. The 56 randomly selected history classes assigned an average of 13 pages of essay writing for the course. The standard deviation for these 56 classes was 5.7 pages. What can be concluded at the αα = 0.10 level of significance? The test statistic    Correct = Incorrect (please show your answer to 3 decimal places.) The p-value =  (Please show your answer to 4 decimal places.)

Five students took a self-confidence test. Their deviation scores were –4, +3, +1, –2, and +2. Assuming that these scores com form a normaldistribution, which deviation represents the highest raw score?

Choose the correct option and explain.

The average McDonald's restaurant generates $2.4 million in sales each year with a standard deviation of 0.7. Carissa wants to know if the average sales generated by McDonald's restaurants in New Mexico is different than the worldwide average. She surveys 18 restaurants in New Mexico and finds the following data (in millions of dollars): 2.1, 2, 2.9, 1.7, 1.8, 2.3, 2.1, 2.1, 3.3, 1.4, 1.6, 1.4, 1.4, 2.3, 2.6, 2.7, 2.7, 1.7 Perform a hypothesis test using a 8% level of significance. Step 1: State the null and alternative hypotheses. Ho: pv 2.4 Ha: Ev 2.4 (So we will be performing a two-tailed test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are normally distributed v with and distribution standard deviation distribution mean Step 3: Find the p-value of the point estimate. P(zv [ p-value = Step 4: Make a Conclusion About the…
