Transcribed Image Text:The average student-loan debt is reported to be $24,805. History has shown that the standard
deviation for all student loan debt has been $3,200. A student believes that the student-loan debt is
lower in her area. She takes a large sample of 53 randomly-selected college students in her area and
determines the sample mean student-loan debt is $24,035 and the standard deviation is $3,250.
Is there sufficient evidence to support the student's claim at a 0.05 significance level? Round answers
to 4 decimals where possible.
1. Determine the null and alternative hypotheses. Fill in one blank for Ho and 2 blanks for Ha
Ho: μ =
H₁:?
2. The Test Statistic type
