Hypothesis Testing Assignment Solution - South University

This document presents a solution to a hypothesis testing assignment, likely for a statistics course. It addresses the core concepts of hypothesis testing, including the null and alternative hypotheses, and the calculation of test statistics. The solution involves determining the critical values and p-values to make a decision about rejecting or failing to reject the null hypothesis. It also discusses Type 1 and Type 2 errors in the context of the assignment. The assignment uses a real-world example to illustrate the concepts, and the final conclusion involves rejecting the null hypothesis. The document includes a reference to the textbook used for the assignment. This solution is ideal for students looking for help with their statistics homework.

HYPOTHESIS TESTING 2
Giving that the Population menu ( μ)= μ. The Standard Deviation, = 4.32
sample mean 1x =4.32, number (N) =100, Null, Ho: = μ
Alternate: H1 :m = μ , Level of Significance, x = 0.05
From standard normal table, two tailed 2 α\2 + 1.95996. Since our test is two- tailed
reject Ho 20< -1.95996 or 20>1.95996
I use test statistics (2) = x-u\cs*d\sqrt (n1)
20= 4.32- μ\(0.67\sqrt (100)
20= 6.78
1201=4.78
The value of 12 d\ at los 5% os 1.95996
(20) =4.78 & (2x) =1.95996
Make the decision:
Since the value of 20> 2x and right here, I have Ho
P-value: two tailed (double the one tail)-Ha (p!=4.78) =0
The value of Po.0>, He we reject Ho
My answer is made from this simple solution
Null, HO: M = μ, Alternate hypothesis: H1 : M! = μ, test statistic: 4.78
conditional value: -1.95996, 1.95996
decision reject HO
P-value : 0

HYPOTHESIS TESTING 3
I found enough evidence to support the claim that
Type 1 Errors happen when I reject a tone null hypothesis
Type 2 Errors happen when I fail to reject a false null hypothesis
So that in this content we reject the null hypothesis, that is type 1 error.
