The 2012 National Health and Nutrition Examination Survey reports a 95%95% confidence interval of 99.899.8 to 102.0102.0 centimeters for the mean waist circumference of adult women in the United States. (a) What is captured by this confidence interval? We are trying to capture the true average waist circumference of adult women in the United States. We are trying to capture the true average waist circumference of adult men in the United States. We are trying to capture the true average waist circumference of adults in the United States. We are trying to capture a average waist circumference of a sample of adult women in the United States.

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

yes
