Question content area top Part 1 In a recent study on world​ happiness, participants were asked to evaluate their current lives on a scale from 0 to​ 10, where 0 represents the worst possible life and 10 represents the best possible life. The responses were normally​ distributed, with a mean of 4.44.4 and a standard deviation of 2.12.1. Answer parts ​(a)dash–​(d) below.       Question content area bottom Part 1 ​(a) Find the probability that a randomly selected study​ participant's response was less than 44.   The probability that a randomly selected study​ participant's response was less than 4 is enter your response here. ​(Round to four decimal places as​ needed.) Part 2 ​(b) Find the probability that a randomly selected study​ participant's response was between 44 and 66.   The probability that a randomly selected study​ participant's response was between 44 and 66 is enter your response here. ​(Round to four decimal places as​ needed.) Part 3 ​(c) Find the probability that a randomly selected study​ participant's response was more than 88.   The probability that a randomly selected study​ participant's response was more than 88 is enter your response here. ​(Round to four decimal places as​ needed.) Part 4 ​(d) Identify any unusual events. Explain your reasoning. Choose the correct answer below.     A. The event in part left parenthesis a right parenthesis(a) is unusual because its probability is less than 0.05.   B. None of the events are unusual because all the probabilities areNone of the events are unusual because all the probabilities are greatergreater than 0.05.   C. The event in part left parenthesis c right parenthesis is unusual because its probability is lessThe event in part (c) is unusual because its probability is less than 0.05.   D. The events in parts left parenthesis a right parenthesis and left parenthesis b right parenthesis(a) and (b) are unusual because their probabilities are less than 0.05.
