The test statistic of z = 2.01 is obtained when testing the claim that $p \ne 0.345$. Find the P-value.

The test statistic of z = -2.50 is obtained when testing the claim that p < 0.75. Find the P-value.

The test statistic of z = 1.00 is obtained when testing the claim that p > 0.3. Find the P-value.

The test statistic of z = 1.00 is obtained when testing the claim that p > 0.3. Using a significance level of $\alpha$ = 0.05, should we reject $H_0$ or should we fail to reject $H_0$?

The test statistic of z = - l .94 is obtained when testing the claim that p = 3 / 8. Find the P-value.

The test statistic of z = -2.50 is obtained when testing the claim that p < 0.75. Using a significance level of $\alpha$ = 0.05, should we reject $H_0$ or should we fail to reject $H_0$ ?

The test statistic of z = 1.00 is obtained when testing the claim that p > 0.3. Find the critical value(s).

The test statistic of z = 2.01 is obtained when testing the claim that $p\ne$0.345. Using a significance level of $\alpha$ = 0.05, should we reject $H_0$ or should we fail to reject $H_0$?

The test statistic of z = 1.00 is obtained when testing the claim that p > 0.3. Using a significance level of $\alpha$ = 0.05, should we reject $H_0$ or should we fail to reject $H_0$ ?

Claim: Fewer than 95% of adults have a cell phone. In a Marist poll of 1128 adults, 87% said that they have a cell phone. Find the value of the test statistic.

Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, or critical value(s), then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Use the P-value method unless your instructor specifies otherwise. Use the normal distribution as an approximation to the binomial distribution.When she was 9 years of age, Emily Rosa did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 280 trials, the touch therapi sts were correct 123 times (based on data in "A Close Look at Therapeutic Touch," Journal of the American Medical Association, Vol. 279, No. 13). Use a 0. LO significance level to test the claim that touch therapists use a method equjvalent to random guesses. Do the results suggest that touch therapists are effective?

Find the inverse of the function. Then graph the function and its inverse on one coordinate system. Show the line of symmetry on the graph.

$$f ( x ) = \frac { x } { 3 } + \frac { 1 } { 3 }$$

The test statistic of z = 2.01 is obtained when testing the claim that $p \ne 0.345$. Find the critical value(s).

The test statistic of z = -2.50 is obtained when testing the claim that p < 0.75. Using a significance level of $\alpha$ = 0.05, should we reject $H_0$ or should we fail to reject $H_0$?
