It has been estimated that between 1945 and 1971, as many as 2 million children were born to mothers treated with diethylstilbestrol (des), a nonsteroidal estrogen recommended for preg- nancy maintenance. the fda banned this drug in 1971 because research indicated a link with the incidence of cervical cancer. the article "effects of prenatal exposure to diethylstilbestrol (des) on hemispheric laterality and spatial ability in human males" (hormones behav., 1992: 62–75) discussed a study in which 10 males exposed to des and their unexposed brothers underwent various tests. this is the sum- mary data on the results of a spatial ability test: x 1⁄4 12: 6 (exposed), y 1⁄4 13: 7, and standard error of mean difference 1⁄4 .5. test at level .05 to see whether exposure is associated with reduced spatial ability by obtaining the p-value.
a. state the relevant hypothesis
b. compute the test statistic value and find the p-value show steps will rate !

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
