1.) an obstetrician wants to determine whether a new diet significantly increase the birth weight of
babies. in 2005, birth weights of full-term babies (gestation period of 37-41 weeks) were normally
distributed, with a mean of 7.53 pounds, according to the national vital statistics report. the
obstetrician randomly selects 51 recently pregnant mothers and persuades them to partake of this new
diet. the obstetrician then records the birth weights of the babies and obtains a sample mean i = 7.79
pounds and a sample standard deviation of s = 1.15 pounds. test the hypothesis that the new diet is
effective, that is, that it results in higher average birth weights. use a = .05.
a.) state the null and alternate hypotheses.
b.) state and sketch the distribution you are using, marking off the critical region(s)-label well.
c.) compute the test statistic. show enough work so that you work can be followed. double-check
using stat capability of your calculator.
d.) state the decision.
e.) state the conclusion.
f.) either compute the p-value or get an interval estimate for it.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
