Question
Suppose you want to test the claim the the paired sample data given below come from a population for which the mean difference is ??=0.
?(68, 73, 84, 88, 85, 88, 56)
y(76, 57, 79, 65, 61, 60, 73)
Use a 0.01 significance level to find the following:
(a) The mean value of the differnces ? for the paired sample data
d¯=
(b) The standard deviation of the differences ? for the paired sample data
??=
(c) The t test statistic
?=
(d) The positive critical value
?=
(e) The negative critical value
?=
(f) Does the test statistic fall in the critical region?
A. No
B. Yes
(g) Construct a 99% conficence interval for the population mean of all differences x−y.
