A sample mean, sample size, and population standard deviation are  provided below.  Use the one-mean z test to perform the required hypothesis test at the 1% signifigance level. Find the test statistic and p-value.  Do we reject or fail to reject? x bar=17 n=36 standard deviation=6 Ho: mean=21 Ha: mean  <21

Teat the claim abouy the population mean, u, at the given level of significance, a, using the given sample statistics. Claim:u=50; a=0.05; o=3.11. Sample statistics: x=48.4, n=71. i) Identify the null and alternative hypothesis. (Do not forget to find the standardized test statistic and critical values) ii) Determine tge outcome and conclusion of the test.

A sample mean, sample size, and population standard deviation are provided below. Use the one-mean z-test to perform the required hypothesis test at the 10% significance level. x=35, n=21, a=5, Ho: μ = 34, H₂: μ#34 The test statistic is z = (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) the null hypothesis. The data sufficient evidence to conclude that the mean is
