Use it to perform ahypothesis test.Many bank employees are paid by the hour. Consider a small bank called BBBanking which is currentlyhiring. During the interviewing process, BBBanking's manager indicates that it pays its hourly tellerscomparable to any other bank. To ensure he is making an accurate statement, he collects a random sampleof full-time hourly tellers' wages. Here are their wages (in dollars per year).21,98517,53117,25418,57520,68818,08222,75317,39219,28219,11418,41819,07719,62616,750Suppose the wages are normally distributed with standard deviation $2000.
