A company makes batteries with an average life span of 300
aksik [14]

Answer:

a) P(z<-0.66) = 0.2546

b) P(-1<z<1) = 0.6826

c) P(z>1.33) = 0.9082

Step-by-step explanation:

Mean = 300

Standard Deviation = 75

a) Less than 250 hours

P(X<250)=?

z = x - mean/ standard deviation

z = 250 - 300 / 75

z = -50/75

z = -0.66

P(X<250) = P(z<-0.66)

Looking for value of z = -0.66 from z score table

P(z<-0.66) = 0.2546

b. Between 225 and 375 hours

P(225<X<375)=?

z = x - mean/ standard deviation

z = 225-300/75

z = -75/75

z = -1

z = x - mean/ standard deviation

z = 375-300/75

z = 75/75

z = 1

P(225<X<375) = P(-1<z<1)

Looking for values from z score table

P(-1<z<1) = P(z<1) - P(z<-1)

P(-1<z<1) = 0.8413 - 0.1587

P(-1<z<1) = 0.6826

c. More than 400 hours

P(X>400) =?

z = x - mean/ standard deviation

z = 400-300/75

z = 100/75

z = 1.33

P(X>400) = P(z>1.33)

Looking for value of z = 1.33 from z-score table

P(z>1.33) = 0.9082

A random generator is used to select an integer from 1 to 3 inclusive. What is the difference between the estimated probability
Assoli18 [71]

Answer:

option no D

Step-by-step explanation:

AS it given that it is a random generator

so it will generate random integers between 1 and 3

so

possible sample space = {1,2,3}

Total no of out comes = 3

Estimated probability that 3 will occur will be obtained by dividing total no of outcomes with total no of possible events to occur

as the occurrence of event is only 1

so

Estimated probability = 1 /3 = 0.33333

Now

The experiment is performed

total outcomes = 14

Total no of like able events that 3 occurred = 4

Actual probability = 4 / 14

                             = 0.2857

Difference between actual and estimated probability is = 0.3333-0.2857

                                                                                            =0.0421

                                                                                           ≅0.04

which is option D
