Consider the following hypothesis test Ho: μ ≥ 10 Ha: μ < 10 A sample of 50 provides a sample mean of 9.46 and sample variance of 4. a) At 5% should the null be rejected? b) Compute the value of the test statistic c) What is the p-value? d) What is your conclusion? Consider the following hypothesis test. Ho: μ = 17 Ha: μ ≠ 17 A sample of 25 gives a sample mean of 14.2 and sample variance of 25. a) At 5% should the null be rejected? b) Compute the value of the test statistic c) What is the p-value? d) What is your conclusion? Explain.

Consider the following hypothesis test; Ho : M > or equal 20 Ha ; M< 20 a sample of 50 provided a sample mean of 19.4. the population standard deviation is 2. a) compute the value of the test statistic b) what is the P-value. c) using a = .05 what is your conclusion? d) what is the rejection rule using the critical value? what is your conclusion?

Consider the following hypothesis test: \[\begin{array}{l}H_{0}: \mu \geq 20 \\H_{\mathrm{a}}: \mu<20\end{array}\] A sample of 50 provided a sample mean of $19.4 .$ The population standard deviation is 2 a. Compute the value of the test statistic. b. What is the $p$ -value? c. $\quad$ Using $a=.05,$ what is your conclusion? d. What is the rejection rule using the critical value? What is your conclusion?
