Answer:
Probability of choosing number = 0.9192
Step-by-step explanation:
Given:
New mean = 87.8
Mean = 85
Standard deviation = 14
Number picked = 49
Find:
Probability of choosing number
Computation:
Probability of choosing number = [New mean - Mean] / [Standard deviation / √Number picked]
Probability of choosing number <= [(87.8-85)]/[(14/7)]
Probability of choosing number = 0.9192
I think 6 of each. I divided 15 by 2, got $7.50. You can buy exactly six magazines w that, and 6.5 granola bars. So six of each.
