Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 640 randomly selected adults showed that 99.3% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim.
The median price of homes in in a certain city was $228,830. A sample of 200 homes sold in a suburb of the city found 113 homes with sales prices over $228,830 and 87 homes with sales prices under $228,830. Can you conclude that the median price of homes in the suburb differs from the median price of homes in the entir city? Use a = 0.05. State the null and alternative hypotheses.

A baseball team claims that the mean length of its games is 2.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≤2.4." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≠2.4." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≥2.4." D. The null hypothesis expressed in words is, "the mean length of a baseball…

What is your decision regarding H0?
In a hypothesis test, H0 is p < 0.45 and Ha is p > 0.45. If the test statistic is z = 1.68, what is the P-value? Draw picture and give P-value only. Do not do rest of testing.
