You want to determine if the average number of cases of west

You want to determine if the average number of cases of west Nile Virus is the state of Georgia is significantly more than 3. Assume the population is normally distributed. State the null and the alternative hypotheses. You are given the following information obtained from a random sample of 4 observations. 25 47 32 56 You want to determine whether or not the mean of the population from which this sample was taken is significantly different from 48. (Assume the population is normally distributed.) State the null and the alternative hypotheses. You are given the following Information obtained from a random sample of 5 observations. Assume the population has a normal distribution. 20 18 17 22 18 You want to determine whether or not the mean of the population from which this sample was taken is significantly less than 21. State the null and the alternative hypotheses.

Solution

12) H0: population mean number of cases of west nile virus in the state of Georgia = 3 ag. H1 : population mean number of cases of west nile virus in the state of Georgia > 3....

13)H0: POPULATION MEAN = 48 ag. H1: POPULATION MEAN NOT EQUAL TO 48......

14) H0 : POPULATION MEAN = 21 ag. H1 : population mean < 21.....
