3. I have got few wrong please help me with them

You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. Hu:p=22 Ha:p:22 A sample of 75 is used and the population standard deviation is 10. Compute the p-value and state your conclusion for each of the following sample results. Use 0! = 0.01. (Round your test statistics to two decimal places and your p-values to four decimal places.) (a) X: 23 Find the value of the test statistic. Find the p-value. pvalue = 0.3865 " State your conclusion. 0 Do not reject H0. There is sufficient evidence to conclude that p 2 22. O Reject H0. There is sufficient evidence to conclude that p 22.
