State the null hypothesis.A student pursuing a degree in English as a second language believes the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak English. To test her claim she randomly selects 373 female factory workers and out of them 43 could not speak English. She then randomly selects 215 male factory workers and out of them 65 could not speak English. Test her claim at .=0.05 to see if she was right.

You define the variable of interest as the strength of the insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks. The accompanying data represent the amount of force required to break a sample of 30 insulators. 1,865 1,706 1,698 1,619 1,609 1,779 1,570 1,693 1,581 1,668 1,898 1,755 1,729 1,698 1,704 1,780 1,883 1,771 1,799 1,867 1,812 1,713 1,754 1,793 1,823 1,791 1,668 1,815 1,677 1,707 Construct a 90% confidence interval for the population mean force. ___ ≤μ≤ ___A manufacturing company produces electric insulators.
