TV advertising agencies face increasing challenges in reaching audience members because viewing TV programs via digital streaming is gaining in popularity. The Harris poll reported on November 13, 2012, that 53% of 2343 American adults surveyed said they have watched digitally streamed TV programming on some type of device. Calculate a confidence interval at the 99% confidence level for the proportion of all adult Americans who watched streamed programming up to that point in time. What is the upper bound of this 99% confidence level for the proportion

99% Confidence interval:  (0.5034,0.5566)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 2343

Proportion of adults who watched digitally streamed TV = 53\%

99% Confidence interval:

Putting the values, we get:

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
