Question

UC.A single thermometer is randomly selected and tested. ethermometers are rejected because they have readings that are too high and another 4.1%are as they have readings that are too low, find the two readings that are cutoff values sepaa 4, 1% of the Poin sun th e rejected thermometers from the others. babi oC interval of acceptable thermometer readings- #11 Points possible: 1 . Total attempts: 1 ts ne t d a Assume that z-scores are normally distributed with a mean of O and a standard deviation of 1. If P(z

Explanation / Answer

P(Z < e) = 0.3103

From standard normal distribution table, take the z value corresponding to 0.3103

z score for 0.3121 = -0.49

z score for 0.3085 = -0.50

(0.3085 + 0.3121)/2 = 0.3103. so, is at the midpint of 0.3121 and 0.3085

So, the z score corresponding to 0.3103 will be the midpoint of -0.49 and -0.5

So, e = (-0.49 -0.5)/2 = -0.495
