The data set has no outliers
The final part of the question is asking;
How much did all (99.7%) of the students spend on textbooks in a semester
Answer:
almost all (99.7%) of the students spent between $165 and $315 on textbooks in a semester.
Step-by-step explanation:
The standard deviation rule describes to us that for distributions that have the normal shape, approximately 99.7% of the observations fall within 3 standard deviations of the mean.
In this question, we are given that; Mean = 240 and Standard deviation= 25
So, 3 standard deviation below the mean = Mean - 3(standard deviation)
= 240 - (3 × 25)
= 240 - 75 = 165
Now, 3 standard deviation above the mean = Mean + 3 standard deviation = 240 + (3 × 25)
= 240 + 75 = 315
So, almost all (99.7%) of the students spent between $165 and $315 on textbooks in a semester.
If 62% of the seats are sold;
100-62= 38% seats still available.
17100=38% seats available
17100/38= seats in 1%
450 seats
In 100%,
450×100=450000 seats total.
