Answer: 1100 boys


Step-by-step explanation:


45% students are girls

45% girls in number = 900

1% be = 900x45= 20

55% students are boys

Answer:

1100

Step-by-step explanation:

The whole school population is represented by 100%, thus

number of girls = 100% - 55 = 45% of population

divide 900 by 45 to find 1% then multiply by 55 to find number of boys

number of boys = \frac{900}{45} × 55 = 1100

David wants to complete a hypothesis test with the least amount of probability for error. If he sets the significance level to 1
Brrunno [24]

Answer:

He could increase the sample size

Step-by-step explanation:

In hypothesis testing, the error associated with the test is affected by a number of factors. The first factor is the level of significance, alpha. This is the probability of type 1 error. The probability of rejecting the null hypothesis when it is indeed true.

The second factor is the size of the sample used. The larger the sample, the smaller the error since the characteristics of the sample will be closer to those of the entire population on which inference is being made

prisoha [69]

Answer:

Midpoint of a line segment with the endpoints A(a1, a2), B(b1, b2) is M(1/2*(a1 + b1), 1/2*(a2 + b2))

So,

(1/2*(-4 + 7), 1/2*(-3 + (-5))) = (1/2*3, 1/2*(-8)) = (1.5, -4)

Answer D is correct.
