I need help, please explain step by step, I need to understand how to solve this problem with a regular calculator, no Excel.

Coffee: The National Coffee Association reported that 61%% of U.5. adults drink coffee daily. A random sample of 250 U.S. adults is selected. [a) Find the mean JA (b) Find the standard deviation an (c) Find the probability that more than 65% of the sampled adults drink coffee daily. (d) Find the probability that the proportion of the sampled adults who drink coffee daily is between 0.59 and 0.68. (e) Find the probability that less than 56% of sampled adults drink coffee dally. (f) Would it be unusual if less than 54%% of the sampled adults drink coffee daily? Part 1 of 6 (2) Find the mean HA. The mean JA is Part 2 of 6 (b) Find the standard deviation or. The standard deviation G Is Homework 2 81 | Page 16 / 27 Part 3 of 6 (c) Find the probability that more than 65% of the sampled adults drink coffee daily. The probability that more than 65% of the sampled adults drink coffee daily is Part 4 of 6 (d) Find the probability that the proportion of the sampled adults who drink coffee daily is between 0.59 and 0.68. The probability that the proportion of the sampled adults who drink coffee dally is between 0.59 and 0.68 is Part 5 of 6 (e) Find the probability that less than 56% of sampled adults drink coffee daily. The probability that less than 56%% of sampled adults drink coffee daily is Part 6 of 6 (f) Would it be unusual If less than 54% of the sampled adults drink coffee daily? It be unusual if less than 549% of the sampled adults drink coffee daily, since the probability is Blank Toalions would
