Question

Suppose a study is done to test the null hypothesis H₀: μ = 100. A random sample of n = 42 observations results in x = 104 and s = 11.

(a) What is the null standard error in this case? (Round your answer to three decimal places.)

(b) Plug numbers into the formula and enter the result in the answer box. (Round your answer to three decimal places.)

Sample statistic − Null value

Null standard error

(c) On the basis of the information given, can the p-value for this test be found? If so, find it. If not, enter NONE in the answer box.

Answer 1

given l = 100 t = 107 5 = 1 , n=42 @ Null standard esere - fn = base = 10697 142 Null value To find I sample statistic - SE 104-100 = 1.697 = 2.356 t-test stat = 2.356 © p-value = p value cants find as we don't know alternative hypother's . NONE
