The product of 4 and a number w is at most 51

1 answer:

4 0

Ok, at most is basically less than or equal to the number, because it means that at most the number is equal to or less. The equation is 4W > 51

After running the t-test provided in the directions, for each of the test variables (AGE, PAEDUC, and EDUC) please provide the M

marishachu [46]

Answer:

11. This is totally correct (See attached image)

12. Consider Age.

Suppose, we want to test H0: mean age(White)=mean age(Black) against H1: mean age(White)>mean age(Black) and we find the one sided p value (which is just half of the 2 tailed p value) less than 5% and hence the difference is significant

Consider Father education.

Suppose, we want to test H0: mean years of father's education(White)=mean years of father's education(Black) against H1: mean years of father's education(White)>mean years of father's education(Black) and we find the one sided p value (which is just half of the 2 tailed p value) less than 5% and hence the difference is significant

Consider Highest year of school completed.

Suppose, we want to test H0: mean completion(White)=mean completion(Black) against H1: mean completion(White)>mean completion(Black) and we find the one sided p value (which is just half of the 2 tailed p value) less than 5% and hence the difference is significant

Thus, we find significant difference with respect to education and life expectancy. However, it is difficult to comment on racial inequality, it requires further information on whether equal opportunity was available for both and some related administrative information.

Based on a survey, assume that 43% of consumers are comfortable having drones deliver their purchases. Suppose that we want to

lutik1710 [3]

Answer:

The probability that exactly three of them are comfortable with delivery by drones is 0.2583.

Step-by-step explanation:

Let X = number of consumers comfortable having drones deliver their purchases.

The probability of the random variable X is, P (X) = p = 0.43.

Then q is, q = 1 - p

A sample of n = 5 consumers are selected.

The random variable X follows a Binomial distribution with parameters n and p.

The pmf of X is:

$P(X=x)={n\choose x}p^{x}(1-p)^{n-x};\ x=0,1,2,3...$

Compute the value of P (X = 3) as follows:

$P(X=3)={5\choose 3}0.43^{3}(1-0.43)^{5-3}\\=10\times 0.079507\times 0.3249\\=0.258318\\\approx0.2583$

Thus, the probability that exactly three of them are comfortable with delivery by drones is 0.2583.
