Use the following information for questions:
A small bakery is trying to predict how many loaves of bread to bake daily. They randomly sample daily sales records from the past year. In these days, the bakery sold between 40 and 80 loaves per day with a 95% confidence interval for the population mean daily loaf demand given by (51, 54) .
-Based on this interval, what is the decision for testing H₀: $\mu$ = 50 versus H_a: $\mu$ $\neq$ 50 at the 10% significance level?

Quizplus · Accepted Answer

The 95% confidence interval for the population mean daily loaf demand does not include the value 50 ($\mu$ = 50), which is the value under the null hypothesis. Since 50 is not within the interval (51, 54), we reject the null hypothesis at the 10% significance level.
