Galina-37 [17]

Answer:

b.0.02

Step-by-step explanation:

As he defined the significance level in α=0.05, and this is a one-side test (as the claim is that the percentage is <em>higher, </em>not lower), any P-value below the significance level shows a significant effect and gives evidence to reject the null hypothesis.

The P-value represents the probability of having this sample statistic, given that the statement of the null hypothesis is true. Then, the lower the P-value, more evident is that the null hypothesis is not correct. This threshold value to reject (or not) the null hypothesis is the significance level.

a) As the significance level is 0.05, a P-value=0.07 would not be low enough to reject the null hypothesis.

c) The magnitude of a P-value has impact on whether he rejects or fails to reject the null hypothesis, as is the value that is compared to the significance level to reject or not the null hypothesis.

PLEASE HELP WILL GIVE BRAINLIEST IF CORRECT
rusak2 [61]

Answer:

To find the simple interest, we multiply 40000 × 0.12 × 10 to get that:

The interest is: $48000.00

Usually now, the interest is added onto the principal to figure some new amount after 10 year(s),

or 40000.00 + 48000.00 = 88000.00. For example:

If you borrowed the $40000.00, you would now owe $88000.00

If you loaned someone $40000.00, you would now be due $88000.00

Step-by-step explanation:

hope this helps!

Let the random variable X be equally likely to assume any of the values 1/14, 1/7, or 3/14. Determine the mean and variance of X
Dimas [21]

Answer:

1/7 ;

0.0034

Step-by-step explanation:

Given that:

X = 1/14, 1/7, 3/14

n = number of observations = 3

Since, probability of X is equally likely ;

P(X) = Σp(x) = 1 ; p(x) = 1/n = 1/3

The mean, m ;

Σx*p(x) = (1/3 * 1/14) + (1/3 * 1/7) + (1/3 * 3/14)

= 1/42 + 1/21 + 3/42

= (1 + 2 + 3) / 42

= 6 / 42

= 1/7

The variance :

Σx²*p(x) - m²

((1/3) * (1/14)^2) + ((1/3) * (1/7)^2) + ((1/3) * (3/14)^2) - (1/7)^2

= 0.0238095 - 0.0204081

= 0.0034014

= 0.0034
