Answer: 9.1 credit hours per semester.

Step-by-step explanation:

  • The sample size[tex](\overline{x})[/tex] is the best point-estimate for the true population mean[tex](\mu)[/tex] ( if true population mean is unknown).

Given : At the local college, by taking a sample of 96 students , study found that students earned an average of 9.1 credit hours per semester.

i.e. [tex]\overline{x}=9.1 [/tex] credit hours per semester.

i.e. [tex]\mu=\overline{x}=9.1[/tex] credit hours per semester.
