Consider the following hypothesis test. Ho: rho = 0.5 Ha: rho not equals 0.5 A sample of 800 is provided and produces a sample proportion of 0.58. Using alpha = 0.05, what is the rejection rule? A. Reject Ho if z < 1.645. B. Reject Ho if z < -1.96 or if z > 1.96. C. Reject Ho if z > 1.96. D. Accept Ha if z < -1.645 What is the standard error of the proportion? A. 0.01549 B. 0.01767 C. 0.01127 D. 0.02283 What is the value of the test statistic? What should you conclude? A. -4.5; reject Ho. B. 2.33; reject Ho. C. 1.58; do not reject Ho. D. 4.52; reject Ho.

Step 1
Given that p = 0.58 and n = 800, SE = sqrt(0.58*(1-0.58)/800) SE = sqrt(0.58*0.42/800) SE = sqrt(0.2436/800) SE = sqrt(0.0003045) SE ≈ 0.01745 Show more…

Consider the following hypothesis test: H0: μ ≤ 26 Ha: μ > 26 A sample of 40 provided a sample mean of 27.4. The population standard deviation is 6. a. Compute the value of the test statistic (to 2 decimals). b. What is the p-value (to 4 decimals)? Use the value of the test statistic rounded to 2 decimal places in your calculations. c. At α = 0.01, what is your conclusion? p-value is greater than 0.01, do not reject H0 d. What is the rejection rule using the critical value? Reject H0 if z is greater than or equal to 2.33 What is your conclusion? 1.48 is greater than 2.33, do not reject H0

Consider the following hypothesis test: H0: μ ≤ 26 Ha: μ > 26 A sample of 50 provided a sample mean of 27.4. The population standard deviation is 6. a. Compute the value of the test statistic (to 2 decimals). b. What is the p-value (to 4 decimals)? Use the value of the test statistic rounded to 2 decimal places in your calculations. c. At α = 0.01, what is your conclusion? p-value is - Select your answer - H0 d. What is the rejection rule using the critical value? Reject H0 if z is - Select your answer - What is your conclusion? - Select your answer - H0

Health Insurance: Administrative Cost The following data are based on information from Domestic Affairs. Let $x$ be the average number of employees in a group health insurance plan, and let $y$ be the average administrative cost as a percentage of claims. $$ \begin{array}{l|rrrrr} \hline x & 3 & 7 & 15 & 35 & 75 \\ \hline y & 40 & 35 & 30 & 25 & 18 \\ \hline \end{array} $$ (a) Make a scatter diagram and draw the line you think best fits the data. (b) Would you say the correlation is low, moderate, or strong? positive or negative? (c) Use a calculator to verify that $\Sigma x=135, \Sigma x^{2}=7133, \Sigma y=148$, $\Sigma y^{2}=4674$, and $\Sigma x y=3040$. Compute $r$. As $x$ increases from 3 to 75 , does the value of $r$ imply that $y$ should tend to increase or decrease? Explain.
