The latest 4K TVs are very sophisticated pieces of technology. They have to be built to a very high standard. All companies employ a quality control person to make random tests regularly to make sure 95% of the 4K TVs they build meet their standards. The null hypothesis of the test is that the proportion of all 4K TVs produced meet a specified standards is equal to 95 percent. The alternative hypothesis is that the proportion of all 4K TVs produced that meet their standards is greater than 95%. Which of the following describes a Type I error that could result from the test?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 360, a standard deviation of 4, and a margin of error of 2.5%
