H0: ≥ 19
Ha: < 19
The sample size is 120 and the population standard deviation is 6. Use = .05.
If the actual population mean is 18, the probability of a Type II error is 0.4286. Suppose the researcher wants to reduce the probability of a Type II error to .10 when the actual population mean is 18. What sample size is recommended? Round your answer to the next whole number.

Consider the following hypothesis test. H0: ≥ 10 H1: <10 The sample size is 120 and the standard deviation of the population is 5. Use a = 0.05. a. If the real value of the population mean is 9, what is the probability that the mean of the sample will lead us not to reject H0? b. What type of error would be committed if the real value of the population mean was 9 and we conclude...

A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corporations. He believes that the mean systolic blood pressure, H. of CEOs of major corporations is less than 132 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test and measures the systolic blood pressures of a random sample of 50 CEOs of major corporations. Suppose that the population of systolic blood...

Your research supervisor wants you to test the null hypothesis H0: μ = 25 against the one-sided alternative hypothesis Ha: μ < 25. The population has a normal distribution with a variance of 16. You are told to use a sample size of 100 and a rejection region of . State the probability of a Type II error for this test of significance to four digits to the right of the decimal point under the alternative hypothesis that μ = 24.

Fowle Marketing Research, Inc., bases charges to a client on the assumption that telephone surveys can be completed in a mean time of 15 minutes or less.
. Fowle Marketing Research, Inc., bases charges to a client on the assumption that telephone surveys can be completed in a mean time of 15 minutes or less. If a longer mean survey time is necessary, a premium rate is charged. A sample of 35 surveys provided the survey times shown in the file named Fowle. Based upon past studies, the population standard deviation is assumed known with σ = 4 minutes. Is the premium rate justified?(a). Formulate the null...

A construction firm thinks that it is receiving 100 steel pipes with an average tensile strength of 10,000 pounds per square inch(lbs p.s.i.).This is the mean,μ.The size of the sample was n=100.The firm also knows that the population standard deviation,sigma,σ,is 400 p.s.i.The firm chooses a confidence interval of 95 %.This is equivalent to a level of significance,α,of 5 %(.05),where the null hypothesis is H0:μ0=10,000 and the alternative hypothesis is H1:μ0≠10,000.The company does not know that the actual, average tensile strength...
