We aim to verify the assertion that generally, 10% of students repeat a course, leading us to this hypothesis setup: Null hypothesis: Alternative hypothesis. The most fitting choice for this scenario is: d) H0:p=0.1 vs. H1:p ≠ 0.1. For this case, the provided information includes: the number of students repeating the course, the selected sample size, and the estimated proportion of repeaters. We are testing the claim that generally, 10% of students retake classes, which will be validated through established hypotheses.

Answer:

Her accumulated earnings for the month total $2208

Step-by-step explanation:

A dental lab technician receives $14 hourly for day shifts and $18 hourly for night shifts.

During one month:

She completed six 4-hour day shifts
