and 10.5 in. (a) Write the formula of the cumulative distribution function of radius of a wheel rim. (b) Determine the proportion of rim whose radius exceeds 10.2 in. (c) What radius is exceeded by 90% of the rim? (d) Determine the mean and variance of radius of wheel rim. (e) What is the expected value of its moment of inertia through center when the mass 3 Ibf s /in. [Hint: Moment of inertia =mass x (radius) ] 40 of the rim is

The area beneath the normal density curve is separated into three regions by the values a and b. Set the mean of the normal density curve to 4.00, the standard deviation to 0.33, the z-value of a to -3.03 and the z-value of b to be 3.03. determine the area to the left of a, the area between a and b, and the area to the right of b.

Is it true that z values have no units of measurements?

Assume two normal distributions where μ1 = 0.0001, σ1 = 0.01, μ2 = -.0002, σ2 = 0.015, and ρ = .45. Using zs = { .814, .259 }, generate z1 and z2.
