Agallup (management consulting firm) poll based on the work and education survey, conducted in august with a random sample of employed adults, aged 18 and older, living in all 50 u. s. states and the district of columbia, revealed that 73% of salary workers are “completely satisfied” with their relations with co-workers. this 73% rate was based on the total sample of 705 salaried employees. from these results, the 95% confidence interval for the population proportion of all salaried workers who are “completely satisfied” with relations with their coworkers is given by (0.6972, 0.7628).1. which of the following corresponds to the value of 0.73? (select all that apply.)a. the population proportionb. the sample proportionc. p with hat on topd. pare the following statements appropriate or inappropriate to say? 2. with 95% confidence, we estimate the population percentage of all salary workers who are “completely satisfied” with relations with their coworkers is between 69.72% and 76.28%.3. if this survey was replicated many times, each replication producing a new sample (of the same size) from which a 95% confidence interval for the population proportion of all salary workers who are “completely satisfied” with relations with their coworkers is computed, then 95% of the resulting confidence intervals would be expected to capture the population proportion of all salary workers who are “completely satisfied” with relations with their coworkers.4. we would estimate that 73% of all salary workers are “completely satisfied” with relations with their coworkers with a 95% margin of error of 3.28%.5. there is a 95% chance that the population proportion of all salary workers who are “completely satisfied” with relations with their coworkers is between 0.6972 and 0.7628.

Aprisoner is trapped in a cell containing three doors. the first door leads to a tunnel that returns him to his cell after two days of travel. the second leads to a tunnel that returns him to his cell after three days of travel. the third door leads immediately to freedom. (a) assuming that the prisoner will always select doors 1, 2 and 3 with probabili- ties 0.5,0.3,0.2 (respectively), what is the expected number of days until he reaches freedom? (b) assuming that the prisoner is always equally likely to choose among those doors that he has not used, what is the expected number of days until he reaches freedom? (in this version, if the prisoner initially tries door 1, for example, then when he returns to the cell, he will now select only from doors 2 and 3.) (c) for parts (a) and (b), find the variance of the number of days until the prisoner reaches freedom. hint for part (b): define ni to be the number of additional days the prisoner spends after initially choosing door i and returning to his cell.
