If the chi-square (x^2) test statistic = 73.7, what is the p-value you would report? Remember to calculate the df first  Choices: A. P > 0.250 B. P = 0.01 C P < 0.001 D. P < 0.002

Round every calculation to 2 decimal points unless the specific question asks for something different. Show answers as decimals and not percents or fractions.

A normal distribution  with a mean of 2mm and a standard deviation of 0.05mm a randomly generated number of 0.71 , need to calculate the standardised Z value, from my notes Z = (actual value - mean)/standard deviation. do i take the randomly generated number of 0.81 as the actual value ?

Suppose we know that the aspirin content of aspirin tablets follows a Normal distribution with standard deviation of o= 5 mg.

If age were held fixed, but a person put on 15 pounds, what would you expect for the corresponding change in systolic blood pressure? (Use 2 decimal places.)If a person kept the same weight but got 15 years older, what would you expect for the corresponding change in systolic blood pressure? (Use 2 decimal places.)(e) Test each coefficient to determine if it is zero or not zero. Use level of significance 5%. (Use 2 decimal places for t and 3 decimal places for the P-value.)   t P value β2     β3

Calculate the t-value for a mean for the following u – u0 = 15.00n = 25sx = 10.00
