(a) Let p be the proportion of all permanent dwellings on the entire reservation that are traditional hogans. Find point estimates for p and q. (Round your answers to four decimal places.)  p ^ = [BLANK-1] q ^ = [BLANK-2] (b) Find a 99% confidence interval for p. Find the maximal margin of error, E. (Round your answer to three decimal places.) E = [BLANK-3] Report the bounds from the 99% confidence interval for p. (Round your answers to three decimal places.) lower limit [BLANK-4] upper limit [BLANK-5]

I will review your answer when I grade your exam.   How hard is it to reach a businessperson by phone? Let p be the proportion of calls to businesspeople for which the caller reaches the person being called on the first try.   (a) If you have no preliminary estimate for p, how many business phone calls should you include in a random sample to be 80% sure that the point estimate  p ^ will be within a distance of 0.07 from p? (Round your answer up to the nearest whole number.) [BLANK-1] phone calls (b) A report states that businesspeople can be reached by a single phone call approximately 15% of the time. Using this (national) estimate for p, answer part (a). (Round your answer up to the nearest whole number.) [BLANK-2] phone calls

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities. It is estimated that 3.6% of the general population will live past their 90th birthday. In a graduating class of 741 high school seniors, find the following probabilities. (Round your answers to four decimal places.) **Enter in a zero, if you have a decimal answer, ie, enter 0.57.     (a) 15 or more will live beyond their 90th birthday [BLANK-1] (b) 30 or more will live beyond their 90th birthday [BLANK-2] (c) between 25 and 35 will live beyond their 90th birthday [BLANK-3] (d) more than 40 will live beyond their 90th birthday [BLANK-4]

A poll asked the question, “What do you think is the most important problem facing this country today?” Twenty-four percent of the respondents answered “crime and violence.” The margin of sampling error was plus or minus 2 percentage points. Following the convention that the margin of error is based on a 95% confidence interval, find a 95% confidence interval for the percentage of the population that would respond “crime and violence” to the question asked by the pollsters.   lower limit [BLANK-1]% upper limit [BLANK-2]%
