Chapter 8, Problem 22P

The U.S. population in selected years between 1815 and 1965 is listed in the table below. Determine a quadratic equation in the form P= a2t2+ a1t+a0, where t is the number of years after 1800 and P is the population in millions, that best fits the data. Use the equation to estimate the population in 1915 (the population was 98.8 millions). Make a plot of the population versus the year that shows the data points and the equation.

    Year 1815 11845 11875 11905 1935 1965
    Population(millions) 8.3 119.7 444.4 883.2 127.1 190.9

Obtain the linear equation for trend for time series with St² = 140, Ey = 16.91 and Σty= 62.02, m n = 7
A quality characteristic of a product is normally distributed with mean μ and standard deviation σ = 1. Speci- fications on the characteristic are 6≤x≤8. A unit that falls within specifications on this quality characteristic results in a profit of Co. However, if x 8, the profit is -C2. Find the value ofμ that maximizes the expected profit.
A) The output voltage of a power supply is normally distributed with mean 5 V and standard deviation 0.02 V. If the lower and upper specifications for voltage are 4.95 V and 5.05 V, respectively, what is the probability that a power supply selected at random conform to the specifications on voltage? B) Continuation of A. Reconsider the power supply manufacturing process in A. Suppose We wanted to improve the process. Can shifting the mean reduce the number of nonconforming units produced? How much would the process variability need to be reduced in order to have all but one out of 1000 units conform to the specifications?
