Problem 1E

A test has power 0.90 when μ = 15. True or false:

a. The probability of rejecting H0 when μ = 15 is 0.90.

b. The probability of making a correct decision when μ = 15 is 0.90.

c. The probability of making a correct decision when μ = 15 is 0.10.

d. The probability that H0 is true when μ = 15 is 0.10.

NONPROBABILITY SAMPLING ● Probability of selecting a person isn’t known ● Cannot calculate the error of estimation ● Convenience sampling: ot representative ● Quota sampling: imilar to convenience sampling ○ Take steps to ensure that a certain number or percentage of people from a particular group are included ● Purposive sampling:hoose certain pockets of people who reflect the views of the entire population ● Economic sample ● Power: the ability to detect an effect ○ Larger the sample size, the greater the likelihood of detecting an effect ○ Effect sizehow strong variables are related
