Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Question

Try to explain

The number of customers, X, arriving in an ATM in the afternoon can be modelled using a Poisson
distribution with mean 6.5. Compute P(X>4) and SD of X.
O P(X>4) = 0.1180, SD = 6.50
P(X>4) = 0.7764, SD = 6.50
P(X>4) = 0.2236, SD = 6.50
P(X>4) = 0.7764, SD = 2.55
O P(X>4) = 0.2236, SD = 2.55

Is there a relation between police protection and fire protection? A random sample of large population areas gave the following information about the number of local police and the number of local fire-fighters (units in thousands). (Reference: Statistical Abstract of the United States.) Use a 5% level of significance to test the claim that there is a monotone relationship (either way) between the ranks of number of police and number of firefighters. (a) Rank-order police using 1 as the largest data value. Also rank-order firefighters using 1 as the largest data value. Then construct a table of ranks to be used for a Spearman rank correlation test. (c) Compute the sample test statistic. (Use 3 decimal places.)

An official knows that o = 8.3 based on the data of students' science test scores since the early 1990's. In one sample, the average scored by a sixth grader in the comprehensive science test is x = 60.5. Construct a 95% confidence interval for the average score that all sixth graders in the district if they took the comprehensive science test. Select one: O a.

A company manufactures tennis balls. When its tennis balls are dropped onto a concrete surface from a height of 100 inches, the company wants the mean height the balls bounce upward to be 54.7 inches. This average is maintained by periodically testing random samples of 25 tennis balls. If the t-value falls between -t, os and to es, then the company will be satisfied that it is manufacturing acceptable tennis balls. A sample of 25 balls is randomly selected and tested. The mean bounce height of the sample is 56.8 inches and the standard deviation is 0.25 inch. Assume the bounce heights are approximately normally distributed. Is the company making acceptable tennis balls? Find -o 95 and to 96 -to 95 = -2.064 to 95 = 2.064 (Round to three decimal places as needed.) Find the t-value. t-value =
