Answer:
First question:
Top 6%: 4.87 ounces
Bottom 6%: 4.75 ounces
Second question:
Top 7%: Score of 649.4.
Step-by-step explanation:
Problems of normally distributed samples can be 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.
For the first problem, we have that:
Top 6%
The value of X when Z has a pvalue of 0.94. This is
Bottom 6%
The value of X when Z has a pvalue of 0.06. This is
For the second problem, we have that:
Top 7%
The value of X when Z has a pvalue of 0.93. This is
It doesn’t tell me what to put
Your answer would be B. You have to multiply the 3 and 2 which is 6 then put the x so 6x. then your multiply 3 and 6 and get 18 so it would be 6x-18.
Answer:
it's 13 if you use the distance formula
