The z-score is the number of standard deviations away from the mean that a data point is. To find the value of z for which 0.9426 of values are within z deviations of the mean, this means that (1 - 0.9426) = 0.0584 are beyond this interval, and this would be divided by 2: 0.0584 / 2 = 0.0292 of values are located below -z, while another 0.0292 is above +z.
Based on z-tables, this occurs at around z = 1.89, so the interval is from -1.89 to 1.89.
Answer:
the question is not correct. please rewrite the question.
1.45 / 3 = 0.48 for 1 pack of crackers.
21.75 / 0.48 = 45.31...so she bought 45 total packs <===
60 x 0.48 = 28.80....so yes, $ 30 would be enough <==
