Answer:
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
At what value should μ be set so that 6 oz cups will overflow only 2 % of the time?
This means that when , Z will have a pvalue of 1-0.02 = 0.98. So when . We have to find .
8/15 * 6/5 * 1/3 = (8 * 6 * 1) / (15 * 5 * 3) = 48/225 = 16/75
It would havs to be four times two minus three.
A= 3,3
B= -2,3
C=-1,-1
D=1,-3
Answer: 13/24
Step-by-step explanation:
The experiment occurred 24 times orange or lime was selected 10+3=13
Probability the next chew will be orange or lime: 13/24
