1.) Part 4?

Coffee: The National Coffee Association reported that 62% of U.S. adults drink coffee daily. A random sample of 300 U.S. adults is selected. Round your answers to at least four decimal places as needed. Part 1 of 6 (a) Find the mean JA. The mean un is 0.62 . Your answer is correct. Part 2 of 6 (b) Find the standard deviation GA. The standard deviation on is | 0.0280 . Your answer is correct. However, you don't need to put zeros at the end of the number. Alternate Answer: The standard deviation on is 0.028. Part 3 of 6 (c) Find the probability that more than 63% of the sampled adults drink coffee daily. The probability that more than 63% of the sampled adults drink coffee daily is 0.3605(d) nd the probability that the proportion of the sampled adults who drink coffee daily is between 0.56 and 0.64. The probability that the proportion of the sampled adults who drink coffee daily is between 0.56 and 0.64 is D . About 5% of employed adults in the United States held multiple jobs. A random sample of 60 employed adults is chosen. Use the TI84 Plus calculator as needed. (a) Is it appropriate to use the normal approximation to nd the probability that less than 8% of the individuals in the sample hold multiple jobs? If so, nd the probability. If not, explain why not. It E appropriate to use the normal curve, since up = 10. l Your answer is incorrect. CDTI'ECI Answer: It is not appropriate to use the normal curve, since up: 3
