Question

A nutritionist is testing whether the variability in daily calcium intake among adults has increased compared to the known standard deviation. The population is assumed to be normally distributed. The nutritionist performs a right-tailed chi-square test using a random sample of 1010  adults. The nutritionist chooses a significance level of 0.100.10. What is the critical value and the rejection region for this right-tailed chi-square test?

Accepted Answer

Critical value: χ0.10,92=14.684\chi_{0.10,9}^2=14.684Rejection region: 14.684"\u003eχ2\u003e14.684\$$chi^2$$\u003e14.684

Answer

Critical value: χ0.10,92=15.987\chi_{0.10,9}^2=15.987Rejection region: χ215.987\$$chi^2$$
