A researcher selects a sample of 30 participants, randomly assigned to one of two groups. She conducts an independent groups t-test at a .05 level of significance. What is the smallest value that the test statistic could be for this test to result in a decision to reject the null hypothesis using a two-tailed test?
A. 2.052
B. 2.042
C. 2.045
D. 2.048

65

step-by-step explanation:

4400

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
