1. If we reject the null hypothesis when the null hypothesis is true, then we have made a Type_______ error.

2. If we don't reject the null hypothesis when the null hypothesis is in error, then we have made a Type_______ error.

3. The engineering school at a major university claims that 20% of its graduates are women. In a graduating class of 210 students, 58 were females. Does this suggest that the school is believable? Use alpha = 0.05. Round ^p to the nearest ten-thousandth when calculating the test statistic.

4. An Airline Claims That The No-Show Rate For Passengers Is Less Than 5%. In A Sample Of 420 Randomly Selected Reservations,19 were no shows.At alpha= 0.01,test the airlines claim.Round p^ to the nearest thousandth when calculating the test statistic.

5. The business college computing center wants to determine the proportion of business students who have laptop computers at home. If the proportion differs from 30%, then the lab will modify a proposed enlargement of its facilities. Suppose a hypothesis test is conducted and the test statistic is 2.5. Find the P-value for a two-tailed test of hypothesis.

6. A local retailer claims that the mean waiting time is less than 8 minutes. A random sample of 20 waiting times has a mean of 6.3 minutes with a standard deviation of 2.1 minutes. At = 0.01, test the retailers claim. Assume the distribution is normally distributed. Round the test statistic to the nearest thousdansth.
