A random sample of size n= 15 obtained from a population that is normally distributed results in a sample mean of 45.8 and sample standard deviation 12.2. An independent sample of size n = 20 obtained from a population that is normally distributed results in a sample mean of 51.9 and sample standard deviation 14.6. Does this constitute sufficient evidence to conclude that the population means differ at the a = 0.05 level of significance? Click here to view the...
If, in a sample of n = 16 selected from a normal population, X = 53 and S = 12, what are the critical values of t if the level of significance, a, is 0.01, the null hypothesis, Ho, is u = 50, and the alternative hypothesis, Hy, is u #50?

A random sample of size n = 13 obtained from a population that is normally distributed results in a sample mean of 45.2 and sample standard deviation 12.6. An independent sample of size n=17 obtained from a population that is normally distributed results in a sample mean of 51.1 and sample standard deviation 14.9. Does this constitute sufficient evidence to conclude that the population means differ at the a= 0.10 level of significance? Click here to view the standard normal...
A sample of 12 radon detectors of a certain type was selected, and each was exposed to 100 pcI/L of radon. The resulting readings were as follows: 105.5 91.4 100.1 91.7 97.0 91.8 97.4 92.9 108.2 100.6 103.8 106.1 in USE SALT (a) Does this data suggest that the population mean reading under these conditions differs from 100? (Use a = 0.05.) State the appropriate null and alternative hypotheses. Ho: 4 = 100 Haul + 100 Ho: 4 = 100...
