Z Test hypothesis tests are also explain in charts in Excel attachment .

Use the given claim to state a null and an alternative hypothesis. Identify which hypothesis represents the claim.
Answers
A. Claim: p < 0.205
Alternative hypothesis
B. Claim: p > 0.70

Null hypothesis

Test the claim about the population mean µ with a z-test using the given sample statistics and level of significance a.
Answers
A. Claim: µ ≠ 0: a = 0.05. Statistics x = -0.69, s = 2.62, n = 60

The null hypothesis tested is
H0: µ = 0
The alternative hypothesis is
H1: µ ≠ 0
The test statistic used is . Given that = -0.69, n = 60, σ = 2.62
Therefore, = -2.04

Rejection Criteria: Reject the null hypothesis, if the absolute value of test statistic is greater than the critical value of Z at the 0.05 significance level.
