The length of time it takes to complete a word puzzle is found to be normally distributed with a mean of 76 seconds and a standard deviation of 12 seconds Using the
50%-34%-14% figures, find the approximate percentages of scores (on time to complete the word puzzie) that will be above or below the following values
(a) Above 100
() Below 76
(b) Below 100
(g) Above 88
(c) Above 64
(h) Below 88
(d) Below 64
0) Above 52
(e) Above 76
) Below 52
(1) Approximately 50% of scores will be below 76.
(Round to the nearest percent as needed.)
(g) Approximately 4.8% of scores will be above 88.
(Round to the nearest percent as needed.)
(h) Appraximately% of scores will be below 88.
(Round to the nearest percent as needed.)
) Approximately% of scores will be above 52
(Round to the nearest percent as needed.)
