Apply t-test to the following data sets and compare it with the value of u=4. Identify the test and find the critical value and state the conclusion a) 2 3 4 5 6 7 b) 1 2 2 5 5 7

a)0.654

b)-0.34

Step-by-step explanation:

a)2 3 4 5 6 7

Standard deviation

Standard deviation

Df = n-1 = 6-1 = 5

Assume α=0.05

So

So, t critical = 2.57

So, t calculated < t critical

b)1 2 2 5 5 7

Standard deviation =

Standard deviation =

Df = n-1 = 6-1 = 5

Assume α=0.05

So,

So, t critical = 2.57

So, t calculated < t critical

drop out of school or go to quizlet, quizlet is better

step-by-step explanation:

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
