1.704 in the standard normal.
- In the standard normal, will the number 1.610 give a higher or lower 1-sided p-value than that given by 1.704? Briefly explain your answer.
- In the t with 63 degrees of freedom, will the number 1.610 give a higher or lower 1-sided p-value than that given by 1.704? Briefly explain your answer.
Homework Answers
Solution:-
a) In the standard normal, the number 1.610 give a higher 1-sided p-value than that given by 1.704.
Since 1.610 lies to the left of the 1.704 in the standard normal distribution, hence one sided p-value for the 1.610 would be higher as comparative to one sided p-value for the 1.704.
b) In the t with 63 degrees of freedom, the number 1.610 give a higher 1-sided p-value than that given by 1.704.
Since 1.610 lies to the left of the 1.704 in the t with 63 degrees of freedom, hence one sided p-value for the 1.610 would be higher as comparative to one sided p-value for the 1.704.

Given X, and x, distributions that are normal or approximately normal with unknown o, and on, the value of t corresponding to X, - X, has a distribution that is approximated by a Student's t distribution. We use the convention that the degrees of freedom is approximately the smaller of n - 1 and n, - 1. However, a more accurate estimate for the appropriate degrees of freedom is given by Satterthwaite's formula: 2 2 xn2 522 +$22) d.f. z...
