A deterministic square wave process Xsquare (t) with period T. Find means, variations, and autocorrelation functions for the following random process with variations of the function described as follows:

Xsquare (t)= 1, 0 < t< T/2
-1, T/2< t< T
Xsquare (t+T), t<=0
Xsquare (t-T), t>=T

a. Square-wave process with random amplitude.
b. Square-wave process with random phase.
c. Square-wave process with random amplitude and phase is:

Amanda went into the grocery business starting with five stores. after one year, she opened two more stores. after two years, she opened two more stores than the previous year. if amanda expands her grocery business following the same pattern, which of the following graphs represents the number of stores she will own over time?

The equation of line wx is y=2x-5. write an equation of a line perpendicular to line wx in slopeintercept form the contains points (-1,-2)

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
