Question 536358: Hi -
Claim: The standard deviation is greater than 5.2 lbs. When a simple random sample of 21 items is taken from a normally distributed population, s - 6.8 lbs.
I have to identify the null and alternative hypothesis, identify the sampling distribution (normal, t, chi-square) of the test statistic.
Thanks! Happy Thanksgiving!

Ho: sigma <= 5.2
Ha: sigma > 5.2 (clsim)
