According to a certain organization, adults worked an average of 1,803 hours last year. Assume the population standard deviation is 380 hours and that a random sample of 50 adults was selected. Complete parts a through e below. a. Calculate the standard error of the mean. a; = 53.74 (Round to two decimal places as needed.) b. What is the probability that the sample mean will be more than 1,810 hours? P 601,810) = 0.4482 (Round to four decimal places as needed.) c. What is the probability that the sample mean will be between 1,770 and 1,790 hours? P (1,770 sis 1,790) = 0.1343 (Round to four decimal places as needed.) d. Would a sample mean of 1,830 hours support the claim made by the organization? Select the correct choice below and ll in the answer box within your choice. (Round to four decimal places as needed.) O A- The probability P (R: 1,830) = . This supports the claim. . This contradicts the claim. O B- The probability P (21,830) = Help me solve this View an example Get more help A Clear all heck
