Answer:
A. Your battery is likely defective since such poor performance is extremely unlikely.
Step-by-step explanation:
When the distribution is normal, we use 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.
If X is more than two standard deviations from the mean, it is considered an unlikely outcome.
In this question, we have that:
Which of the following conclusions is the most appropriate given this information?
Lasted 400 hours, so X = 400.
4 standard deviations from the mean, so unlikely.
So the correct answer is:
A. Your battery is likely defective since such poor performance is extremely unlikely.
All the values of the <em>x</em> <em> </em>for the given function are and
.
Given-
Given function is,
Rewrite the equation,
Let <em>u </em>in place of and rewrite the equation in the form of u,
Break the 95 in factors and rewrite the equation,
Replace the value of u with ,
It is known that If any individual factor on the left side of the equation is equal to zero then the entire expression will be equal to zero. therefore we get,
further, solve it,
And another factor is
Hence, all the values of the <em>x </em>for the given function are
and
