An institute reported that 63% of its members indicate that lack of ethical culture within financial firms has contributed most to the lack of trust in the financial industry. Suppose that you select a sample of 100 institute members. Complete parts (a) through (d) below. EXEDD a. What is the probability that the sample percentage indicating that lack of ethical culture within financial firms has contributed the most to the lack of trust in the financial industry will be between 58% and 66% ? 0.5832 (Type an integer or decimal rounded to four decimal places as needed.) b. The probability is 70% that the sample percentage will be contained within what symmetrical limits of the population percentage? The probability is 70% that the sample percentage will be contained above % and below% (Type integers or decimals rounded to one decimal place as needed.)
