Question 44671: Hi could you help me wit this problem
Let z be a standard normal random variable. Determine the value of c such that
p(1.05_ carry your intermediate computations to at least four decimal places. Round your answer to at least two decimal places
Thanks for the help

You can put this solution on YOUR website!
Let z be a standard normal random variable. Determine the value of c such that
p(1.05_ Draw the normal curve and draw a vertical line at z=1.05.
Draw a vertical line at z=0
1st: Find the area between z=0 and z=1.05
I get 0.3531
2nd: Add the area 0.1246 to get 0.4777
3rd: Use your z-chart to find the z value
corresponding to an area of 0.4777 to the
right of z=0.
I get z=2.008
You could also use InVNorm(0.9777) if you
have a TI calculator.
