- You are testing the claim that the proportion of men who own cats is larger than the proportion of women who own cats.You sample 60 men, and 50% own cats.You sample 140 women, and 20% own cats.Find the test statistic, rounded to two decimal places.A study has found that 85% of adults get their news on a mobile device. You randomly survey 35 adults and have found that 30 of them indeed get their news on a mobile device. What is the test statistic for this scenario? Round p to the hundredths place before completing your calculations.Identify the P-value. What is the conclusion for this test?
- Twenty years ago, 52% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 281 of 800 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the a=0.1 level of significance. *** Because npo (1-Po) = 199.7 less than 5% of the population size, and the sample can be reasonably assumed to be random, the 10, the sample size is requirements for testing the hypothesis are satisfied.

What is the confidence level? Determine the value of α.The average home in the US is expected to cost $240,000. A random sample of 56 homes sold this month showed average price of $232,000. Assume you have access to this data. We are interested in determining cost if the cost of average home has decreased this month. If the test statistic is -1.66 what is the p-value?
- According to a report on consumer fraud and identity theft, 20% of all complaints for a year were for identity theft. In that year, California had 724 complaints of identity theft out of 3466 consumer complaints. Does this data provide enough evidence to show that California had a higher proportion of identity theft than 20%? Test at the 5% level. State the hypotheses. Ho: P ? ✓ Ha: P?V Calculate the test statistic. Round to four decimal places. Ô = Calculate the standardized test statistic. Round to three decimal places. Z= Find the p-value.

The sample result was that 304 of the 977 people responded "always." Calculate the value of the test statistic by hand. Round the sample proportion and the hypothesized value of the proportion to THREE decimal places. Round the final answer to TWO decimal places.According to a report on consumer fraud and identity theft, 20% of all complaints for a year were for identity theft.
