According to the May 16,2017 report by Pew Research, 45% of US adults say solar energy is very effective in minimizing air pollution. A sample of 160 U. S adults is surveyed. Let be the sample proportion of Americans who believe solar energy is very effective in minimizing air pollution. What is the population proportion?

What is the sample size?

Can the normal approximation be used with this distribution?

What is the mean of the sampling proportion?

What is the standard deviation of the sampling proportion?

What is the probability that no more than 76 U. S adults of the 160 surveyed believe solar energy is very effective in minimizing air pollution?

- What is p hat ?
- What is the z-score?
- What is the probability that no more than 76 U. S. adults of the 160 surveyed believe solar energy is very effective in minimizing air pollution?

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

here try this one

3a-24=0

step-by-step explanation:

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.
