Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean time before failure of 40 months with a standard deviation of 6 months.
This means that
What should be the warranty period, in months, so that the manufacturer will not have more than 10% of the blenders returned?
The warranty period should be the 10th percentile, which is X when Z has a p-value of 0.1, so X when Z = -1.28.
The warranty period should be of 32 months.
Answer:
Option (3)
Step-by-step explanation:
Given functions are,
f(x) =
g(x) = log(2x)
By using a graphing utility we can draw the graphs of the given system of equations.
Common points of the graph will be the solutions of the equations,
From the graph attached,
Solution of the functions is → (0.937, 0.273)
→ (0.9, 0.3)
Option (3) will be the answer.
