As a research consultant for a Texan nonprofit animal shelter, you confirmed cases of the Dog for a sample of counties in the state of Texas, including Potter, Randall, Roberts, Sherman, Swisher, and WheelerAs , you want to determine if the average number of cases of the Dog Flu virus in the state of Texas is significantly more than 3. Assume the population is normally distributed (10 points)

State the null and the alternative hypotheses .

b. Determine the test statistic using the formula below if the sample mean is 4 and the sample standard deviation is 1.265 . t= overline X - mu s sqrt N

What is the degrees of freedom ?

d. Circle the p -value (s ) using the t table below using DF above and T statistic
