5 ?(c) Based on your answer to part (b), choose what can be concluded, at the 0.10 level of significance, about the claim made by Jessica.O Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. So, there is enoughevidence to support the claim that the mean number of cases directly generated by one previous case is greater than 1.2.Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. So, there is notenough evidence to support the claim that the mean number of cases directly generated by one previous case is greaterthan 1.2.Since the p-value is greater than the level of significance, the null hypothesis is rejected. So, there is enough evidence tosupport the claim that the mean number of cases directly generated by one previous case is greater than 1.2.Since the p-value is greater than the level of significance, the null hypothesis is not rejected. So, there is not enoughevidence to support the claim that the mean number of cases directly generated by one previous case is greater than 1.2. An important measure in the study of contagious infectious diseases is the number of cases directly generated by one previous case. Jessica is an epidemiologiststudying the spread of an infectious disease in her country. She claimed that the mean number of cases directly generated by one previous case is now greaterthan 1.2. A study of 12 randomly selected cases of the disease is conducted and finds the sample mean number of cases directly generated by one previouscase to be 1.5 with a sample standard deviation of 0.7. Assume that the population of the number of cases directly generated by one previous case isapproximately normally distributed.Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support the claim that u, the meannumber of cases directly generated by one previous case, is greater than 1.2.(a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test.Ho: 1H: 0OSOD=D0

These next questions come after part B. Which of the statements correctly describes the relationship between the mean and median in the histogram of the number of servings of fruit per day claimed by the 7474 seventeen‑year‑old girls? A) The mean and median are about equal because the distribution is right‑skewed. B) The mean is larger than the median because the distribution is right‑skewed. C) The median is larger than the mean because the distribution is right‑skewed. D) There is not enough information to tell us about the relationship between the mean and median in the histogram. (c) In general, you cannot find the exact values of median, quartiles, or mean from the histogram. What is special about the histogram of the number of servings of fruit that allows you to do this?
