The daily high temperature on October 31 in a certain city is normally distributed with µ = 50 and σ = 8 . What is the probabili
tatyana61 [14]

Answer:

0.5328

Step-by-step explanation:

µ = 50

σ = 8

We are supposed to find the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees

P(46 < x< 58)

Formula : Z=\frac{x-\mu}{\sigma}

at x = 46

Z=\frac{46-50}{8}

Z=-0.5

Refer the z table for p value

p value = 0.3085

at x = 58

Z=\frac{58-50}{8}

Z=1

Refer the z table for p value

p value = 0.8413

P(46 < x< 58)=P(x

Hence the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees is 0.5328
