    What percent of the adults spend more than $2,600 per year on reading and enterta
    According to a government study among adults in the 25- to 34-year age group, the mean amount spent per year on reading and entertainment is $2,020. Assume that the distribution of the amounts spent follows the normal distribution with a standard deviation of $456. (Round z-score computation to 2 decimal places and your final answer to 2 decimal places. Omit the "%" sign in your response.)

    (a) What percent of the adults spend more than $2,600 per year on reading and entertainment?



    (b) What percent spend between $2,600 and $2,900 per year on reading and entertainment?



    (c) What percent spend less than $1,200 per year on reading and entertainment?

    I guess you expect us to fill in your blanks. I see you left enough room for answers, which isn't going to happen. We do not homework assignments for students when they are expected to study and answer themselves. This is in our forum basics.

    If you care to answer yourself, we will let you know if the answer is correct or not.
