Asurvey conducted in july 2015 asked a random sample of american adults whether they had ever used online dating (either an online dating site or a dating app on their cell phone). the survey included 411 adults between the ages of 55 and 64, and 50 of them said that they had used online dating. if we use this sample to estimate the proportion of all american adults ages 55 to 64 to use online dating, the standard error is 0.016. find a 99% confidence interval for the proportion of all us adults ages 55 to 64 to use online dating? round your answers to three decimal places.

Step-by-step explanation:

Let be the sample proportion.

As per given , we have

n= 411

Standard error : se=0.016

Critical value for 99% confidence :

Confidence interval for population proportion :-

Hence, the 99% confidence interval for the proportion of all US adults ages 55 to 64 to use online dating :

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
