Question 7 0 out of 0.66667 points Find the area under the normal curve with mean 45 and standard deviation 3.5 to the right
Question 7 0 out of 0.66667 points Find the area under the normal curve with mean 45 and standard deviation 3.5 to the right of x148 Round to four decimal places. Selected Answer: [None Given Response To find the area to the right of an x-value, use the Normalodt function on your calculator. You are given the lower bound, and you can either type in Feedback: 1E99 to represent infinity, or you can use a very large number like 100,000. Use the mean and standard deviation given instead of 0 and 1 Question 8 0 out of 0.66667 points Find the area under the normal curve with mean 45 and standard deviation 3.5 between x 42.1 and x 50.3. Round to four decimal places. Selected Answer: [None Given Response To find the area to the between x-values, use the Normalcdt function on your calculator. You are given the lower and upper bounds. Use the Feedback: mean and standard deviation given instead of O and 1

Answers

Solution

given : mean (μ ) 45, standard deviation (o) 3.5

formula :

Question 7

P(z > 48) => P (Z μ> 48-45 3.5

Pz 0.86)

0.1957 (from-table)

Question 8

P(42.1 <r < 50.3)s? (42.3.545 < Ζσμ < 50.3.545)

P-0.83<1.51)

P(z < 1.51) _ P(z <-0.83)

=0.9350-0.2037\;(from\;z-table)

=\mathbf{{\color{Red} 0.7313}}
