Question

The following is an appropriate statement of the null and alternate hypotheses for a test of a population mean: H0 : μ = 45 HA : μ < 50

Quizplus · Accepted Answer

The null hypothesis (H0) states that the population mean (μ) is equal to 45, while the alternate hypothesis (HA) states that the population mean is less than 50. This is an appropriate statement of the hypotheses for a test of a population mean because the null hypothesis is specific and the alternate hypothesis is one-sided, indicating that the researcher is interested in testing whether the population mean is less than 50.
