10.106 public health and nutrition over the last decade, many americans have been able to stop smoking. however, a recent survey suggests that asthmatic children are more likely to be exposed to second-hand smoke than children without asthma.19 in a random sample of 300 children without asthma, 132 were regularly exposed to second-hand smoke, and in a random sample of 325 children with asthma, 177 were regularly exposed to second-hand smoke. is there any evidence to suggest that the proportion of children with asthma who are exposed to second-hand smoke is greater than the proportion for children without asthma? use a 5 0.01.

There is no significant evidence at 0.01 significance level, to suggest that the proportion of children with asthma who are exposed to second-hand smoke is greater than the proportion for children without asthma

Step-by-step explanation:

the proportion of children with asthma who are exposed to second-hand smoke is equal the proportion for children without asthma

the proportion of children with asthma who are exposed to second-hand smoke is greater than the proportion for children without asthma

Test statistic can be calculated using the formula

z= where

Then z= ≈1.679

P-value of test statistic is  ≈0.047. Since 0.047>0.01 (significance level) we fail to reject the null hypothesis.

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
