In order to test HO: µ0 = 40 versus H1: µ ≠ 40, a random sample of size n = 25 is obtained from a normal population with a known σ = 6. My x-BAR mean is 42.3 from my sample. Using a TI 83/84 calculator, calculate my P-value with the appropriate Hypothesis Test. Use a critical level α = 0.01 and decide to Accept or Reject HO with the valid reason for the decision. A. My P-value greater than...

The σ population standard deviation is unknown. You collected a simple random sample of the cents portions from 100 checks and from 100 credit card charges. The cents portions of the checks have a mean of 23.8 cents and a standard deviation of 32.0 cents. The cents portions of the credit charges have a mean of 47.6 cents and a standard deviation of 33.5 cents. Use an α = 0.05 level to test the claim that the cents portions of...

To test Ho: = 50 versus H=50, a simple random sample of size n = 40 is obtained. Complete parts (a) through below Click the icon to view the table of critical t-values (a) Does the population have to be normally distributed to test this hypothesis by using t-distribution methods? Why? O A. No-there are no constraints in order to perform a hypothesis test. O B. No-since the sample size is at least 30, the underlying population does not need...

To test Ho: σ=4.6 versus H1: σ≠4.6, a random sample of size n=11 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s=5.6, compute the test statistic. (b) If the researcher decides to test this hypothesis at the α=0.01 level of significance, use technology to determine the P-value. (c) Will the researcher reject the null hypothesis?

A random sample of 40 binomial trials resulted in 16 successes. Test the claim that the population proportion of successes does not equal 0.50. Use a level of significance of 0.05. (a) Can a normal distribution be used for the p̂ distribution? Explain. Yes, np and nq are both less than 5.No, np is greater than 5, but nq is less than 5. No, nq is greater than 5, but np is less than 5.Yes, np and nq are both greater...
