Statistics show that the average person sleeps 8 hours per day.A researcher thinks that university students sleep less than thehypothesized population mean of 8 hours. To test her hypothesis,she surveys 20 university students to see how many hours theysleep. Reported hours of sleep per night: Generate your null andalternative hypotheses and write them below.
Test for significant difference in sleep duration using theOne-Samples T-Test. Use a two-tailed test at the 0.05 level ofsignificance. H0:____=8______H1:____<8_____________________________________________
If you are not sure how to generate the hypotheses, please readthe case above again and watch this video: (you can watch the entire series tolearn more)
