Best ResponseYou've already chosen the best response.1mean = 4.5 standard deviation = 0.5 zscore for observation 3.75 is given by \[\frac{3.754.5}{0.5} = 1.5 \]

Best ResponseYou've already chosen the best response.1i have worked zscore for the observation 3.75 see if u can work the zscore for the observation 5

Best ResponseYou've already chosen the best response.1so we have below so far : zscore for observation 3.75 is ` 1.5` zscore for observation 5 is `1`

Best ResponseYou've already chosen the best response.1now open ur ztable, and find the areas corresponding to these zscores

Best ResponseYou've already chosen the best response.1subtract both to get the percentage of works getting paid between 3.75 and 5

Best ResponseYou've already chosen the best response.1area for the zscore of 1.5 is `0.06681` area for the zscore of 1 is `0.84134` subtract to get the percentage of workers that get paid between 3.75 and 5
