health insurance companies

A Harris poll was taken to determine which of 13 major industries are doing a good job of serving their customers. Among the industries rated most highly by Americans for serving their customers were computer hardware and software companies, car manufacturers, and airlines. The industries rated lowest on serving their customers were tobacco companies, managed care providers, and health insurance companies. Seventy-one percent of those polled responded that airlines are doing a good job serving their customers. Suppose due to rising ticket prices, a researcher feels that this figure is now too high. He takes a poll of 463 Americans, and 324 say that the airlines are doing a good job of serving their customers. Does the survey show enough evidence to declare that the proportion of Americans saying that the airlines are doing a good job of serving their customers is significantly lower than stated in the Harris poll? Let alpha equal .10. If the researcher fails to reject the null hypothesis and if the figure is actually 69% now, what is the probability of committing a Type II error? What is the probability of committing a Type II error if the figure is really 66%? 60%?
