“Untitled.” by Stephen Chen lye often wondered how software is released and sold to the public. ironically, I work foi a company that sells products with knoisii problems. Unfortunately, most of the problems aze difficult to c,eate, which makes them difficult to fbc. I usually use the test program X, which tests the product, to ny to create a specific problem. When the test program Is run ro make an error occur, the likelihood of generating an error Is 1%. So, aimed with this knowledge, I wrote a new test program Y that will generate the same error that test program X creates, but more often. To find out If m test program Is better than the original, so that I can convince the management that [m right, I ran my test piogram to find out how often I can generate the same error. When I ran my test program 50 times, I generated the error twice. While this may not seem much better, I chink that I can convince the management to use my test program instead of the original test program. Am I right?

A research center claims that
30%
of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of
1100
adults in that country,
34%
say that they would travel into space on a commercial flight if they could afford it. At
α=0.05,
is there enough evidence to reject the research center's claim? Complete parts (a) through (d) below.

The manufacturer of a certain engine treatment claims that if you add their product to your engine, it will be protected from excessive wear. An infomercial claims that a woman drove
3
hours without oil, thanks to the engine treatment. A magazine tested engines in which they added the treatment to the motor oil, ran the engines, drained the oil, and then determined the time until the engines seized. Complete parts (a) and (b) below.
(a) Determine the null and alternative hypotheses that the magazine will test.
