Answer:
The minimum level for which the battery pack will be classified as highly sought-after class is 2.42 hours
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:

What is the minimum level for which the battery pack will be classified as highly sought-after class
At least the 100-10 = 90th percentile, which is the value of X when Z has a pvalue of 0.9. So it is X when Z = 1.28.




The minimum level for which the battery pack will be classified as highly sought-after class is 2.42 hours

Answer:
Step-by-step explanation:
there are 4 sixes soo

Answer:
1) = 0.175
2) = 0.244
3) = 0.168
Step-by-step explanation:
Experimental, not theoretical, so we use the results table.
1. P(3 n Tails) = 62/(53 + 65 + 49 + 71 + 54 + 62) = 0.175
2. P(Woman n Up) = 39/(36 + 43 + 39 + 42) = 0.244
3. P(Tuna n Wheat Bread) = 23/(22 + 24 + 21 + 22 + 25 + 23) = 0.168
