Assume that females have pulse rates that are normally distributed with a mean of μ= 75.0 beats per minute and a standard deviation of σ= 12.5 beats per minute. Part A- If 1 adult female is randomly​ selected, find the probability that her pulse rate is less than 82 beats per minute.
ALREADY COMPLETED, probability 0.7123

Part B- If 4 adult females are randomly​ selected, find the probability that they have pulse rates with a mean less than 82 beats per minute.
NOT COMPLETED, need probability!!

Any help would be appreciated. Thank you so much

You are remodeling your kitchen. you’ve contacted two tiling companies who gladly told you how long it took their workers to tile of a similar size jim completed half the floor in 8 hours. pete completed half of the other floor in 7 hours. if pete can lay 20 more tiles per hour than jim, at what rate can jim lay tiles

Which of the following statements are true? (select all that apply.) a quasi-static process is one in which the system is never far from being in equilibrium. when a system can go from state 1 to state 2 by several different processes, the amount of heat absorbed by the system will be the same for all processes. the internal energy of a given amount of an ideal gas depends only on its absolute temperature. when a system can go from state 1 to state 2 by several different processes, the work done on the system will be the same for all processes. when a system can go from state 1 to state 2 by several different processes, the change in the internal energy of the system will be the same for all processes. for any substance that expands when heated, its cp is greater than its cv.
