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
Solve
![3
A psychologist wants to test whether there is any difference in puzzle-solving abilities between boys and girls. Independent samples of eleven boys and fourteen
girls were chosen at random. The boys took a mean of 42 minutes to solve a certain puzzle, with a standard deviation of 5.2 minutes. The girls took a mean of
42 minutes to solve the same puzzle, with a standard deviation of 4.8 minutes. Assume that the two populations of completion times are normally distributed,
and that the population variances are equal. Can we conclude, at the 0.01 level of significance, that the mean puzzle-solving times for boys, H, differs from the
mean puzzle-solving times for girls, µ,?
Perform a two-tailed test. Then fill in the table below.
Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
The null hypothesis:
H:0
H 0
The alternative hypothesis:
OSO
The type of test statistic:
(Choose one) v
O<O
The value of the test statistic:
