The College Board reported that 58.7% of all students who took the 2010 AP Statistics exam earned scores of 3 or higher. One teacher wondered if the performance of her school was better. She believed that year's students to be typical of those who will take AP Stats at that school and was pleased when 34 of her 54 students achieved scores of 3 or better. Ca she clain that her school is better? To verify her clain, test the following hypotheses at Alpha =5%. Ho:P = 0.587 vs Ho:P>0.587

Perform the test of hypothesis on the following scenarios. A brand of powdered milk is advertised as having a net weight of 250 grams. A curious consumer obtained the net weight of 10 randomly selected cans. The values obtained are 256, 248, 242, 245, 246, 248, 250, 255, 243, and 249 grams. Is there reason to believe that the average net weight of the powdered milk cans is less than 250 grams at 10% level of significance? Assume the net weight is normally distributed with unknown population variance. Note: pls follow the given steps in the photo attached
A claim is made that the proportion of college students who have Netflix accounts is 0.92. Mateo believes this claimed value is too high. He is able to survey a random sample of 180 college students, and he finds that the sample proportion who have Netflix accounts is 0.88. Mateo proceeds to use this data to conduct a hypothesis test. Based on this information, which one of the following statements is correct? The P-value will be smaller than 0.01 but larger than 0. The P-value will be between 0.01 and 0.05. The P-value will be between 0.05 and 0.10. The P-value will be larger than 0.10. The P-value will be negative.

A company which designs sports shoes has made an improvement to their popular running shoe. They hope that athletes wearing the new running shoe will be able to run faster over short distances. They will use a paired sample to determine whether the mean time to run 100 meters for sprinters wearing the new running shoe is less than the mean time to run the 100 meters for sprinters wearing the old running shoe. Determine the null and alternative hypotheses for the proposed hypothesis test. O A. Let u, denote the mean time to run 100 meters for sprinters wearing the new running shoe and let u, denote the mean time to run 100 meters for sprinters wearing the old running shoe. The null and alternative hypotheses are Ho: H1 H2 O B.
