Suppose you are a wildlife biologist and you are trying to understand the level of phytoplankton cells in the Delaware river. it is generally considered that the mean of the population is greater than or equal to 52.3 cells per mL. You want to test whether the mean population is this amount. you randomly take a sample of 20 cells. The mean of this sample is 20.265 cells per mL and the standard deviation is 19.76 cells per mL. Perform the test hypothesis using the significance level of 52.3 c/mL by completing the following steps

Question 1.Describe your null and alternative hypothesis in words.

Question 2.Describe your null and alternative hypothesis using symbols.

Question 3. Select the significance level.

Question 5.Select an appropriate test, calculate the test statistic, and p-value using JMP and report the values

Test statistic:

P-value:

Question 6. Determine whether you should reject or not to reject the null hypothesis based on the pvalue. State the reason to support your answer.

Question 7. Describe your conclusion in words in the context of your research question
