A spokesperson from the National Rifle Association (NRA) states that 45% of the households in the United States contain at least one firearm. Assume that this is your population value. Your goal was to take a random sample of 200 homes, but your research yielded only 29 responses. And you find out that only about 23% of them contain a firearm. You want to test the null hypothesis that the population proportion is 45% against the alternative that it is less than that. You set your alpha at .01. Required:
With n=29, you will use the t-statistic and the sampling distribution of the t to perform the hypothesis test.

hi there!

the answer will be d: 2

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

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 %
