QUESTION 4 A random sample was selected from an animal population to measure the blood viscosity. Using SPSS, a statistical hypothesis was performed to test the blood viscosity mean over the population under significant level 5% and the results related that test are given below dt One-Sample Test Test Value 8.3 Sig Mean (2 Difference talled) 95% Confidence Interval of the Difference Lower Upper 2.066 6 084 2.01429 - 3709 4.3995 blood viscosity Fill in the missing blanks: 1. The assumptions for using this test are: The population is variance is simple random sample, and the sample size less than 30. 2. SPSS command for the test: Analyze One Sample T-test 3. The decision is: since the p-value= then we the null hypothesis and decide that the mean equals to under a =0.05
