Answer:

Step-by-step explanation:

Given that in a randomized controlled trial in Kenya, insecticide treated bednets were tested as a way to reduce malaria. Among 343 infants using bednets, 15 developed malaria. Among 294 infants not using bednets, 27 developed malaria.

H0: p1=p2

H1: p1 <p2

(one tailed test)

p1 = 15/343:p2 =27/294:

Difference 4.813 %

95% CI 0.9160% to 9.0217%

Chi-squared 5.947

DF  1

Significance level P = 0.0073

Since p <0.01 we reject null hypothesis.

to make an apple pie, mimi needs 2 cups of flour and 3 cups of apples. how many cups of ingredients does mimi need to make 5 pie
Lady_Fox [76]
For one apple pie, Mimi needs 2 cups of flour and 3 cups of apples, which is 5 cups in all, in order to produce how many cups she would need to make five pies you simply times the number given, number of cups, by 5. So you times 2 by 5, which is 10 and 3 by 5, which is 15 and together that makes 25 cups, 10 cups of flour and 15 cups of apples. If you had three cups of flour and needed to make 20 pies, all you would do is times three by 20, which is 60. 

Hope I explained this correctly, if you need any more help, please ask.

Jack jogs at an average speed of 40 m/min. How far does he<br> jog in 1.2 hours?<br> m
marusya05 [52]
So basically you would create an equation from y=mx+b, so you would put 40 in for m and to find x you convert 1.2 hours into minutes which is 72 minutes. so multiply 40 times 72 and that’s how far Jack will be i believe. Jack jogged 2,880m/min. Hope it’s correct.
