μ=30, σ=5, z=1.3.
We use the formula for normal distribution:
z=xμσ
x=σz+μ
x=5(1.3)+30
x=6.5+30
x=36.5
The raw score corresponding to z=1.3 for normal distribution with μ=30, σ=5 is 36.5.

The manager of the store in the preceding exercise calculated the residual for each point in the scatterplot and made a dotplot of the residuals.
The distribution of residuals is roughly Normal with a mean of $0 and standard deviation of $22.92.
The middle 95% of residuals should be between which two values? Use this information to give an interval of plausible values for the weekly sales revenue if 5 linear feet are allocated to the stores

An important factor in solid missile fuel is the particle size distribution. Significant problems occur if the particle sizes are too large. From production data in the past, it has been determined that the particle size (in micrometers) distribution is characterized by f(x)=3x4,for x>1,f(x)=0, elsewhere.
a) Verify that this is a valid density function.
b) Evalute F(x).
c) What is the probability that a random particle from the manufactured fuel exceeds 4 micrometers?

A flowerpot accidentally falls off the window of a condominium unit. Your unit is located below where the flowerpot had fallen. Your window measures to be 1.60 m tall, and the time it takes the flowerpot to move past your window is 0.150 s (from the top part to the bottom part of the window). How high from the top of your window did the flowerpot fell off?

-The line of symmetry for all normal distributions is x = 0.
-On any normal distribution curve, you can find data values more than 5 standard deviations above the mean.
-The x-axis is a horizontal asymptote for all normal distributions.
