The null and alternate hypotheses are: HO: Haso H:Ha> The following sample information shows the number of defective units produced on the day shift and the afternoon shift for a sample of four days last month. Day shift Afternoon shift 11 10 10 12 14 12 17 15 At the 0.100 significance level, can we conclude there are more defects produced on the day shit? Hint: For the calculations, assume the day shift as the first sample. a. State the...

The null and alternate hypotheses are: H0: ?1 ? ?2 H1: ?1 > ?2 A random sample of 24 items from the first population showed a mean of 113 and a standard deviation of 13. A sample of 18 items for the second population showed a mean of 103 and a standard deviation of 14. A) Use the 0.05 significant level. Find the degrees of freedom for unequal variance test. (Round down your answer to the nearest whole number.) B)...
