Suppose that you have the following function. void mystery(int& one, int two) { int temp temp = one; one = two; two = temp;
vlada-n [284]

Answer:

x = 15 and y = 10

Step-by-step explanation:

It is assumed that 'x' and 'y' are declared as '10' and '15' respectively. Then following the mystery(x, y) function which is pass 10 and 15 as parameter. Then we can follow the logic of the mystery function.

First, temp is assigned to one; that is temp = 10

Secondly, one is assigned to two; that is one = 15

Thirdly, two is assigned to temp; that is two = 10.

Since x and y is same as one and two; we say:

x = one = 15  and

y = two = 10.

In 1995, the moose population in a park was measured to be 1800. By 1998, the population was measured again to be 2400. If the p
Shalnov [3]

The linear equation for the variation of population is p = 200t + 1800.

<h3>What is an equation?</h3>

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The formula for an equation in intercept form will be given as below:-

y = mx + c.

It is given that In 1995, the moose population in a park was measured to be 1800. By 1998, the population was measured again to be 2400.

Write the linear equation for population variation.

p = mt + c

m = Rate of change = ( 2400 - 1800 ) / 3 = 200, put the value in the equation.

p = 200t + c

Put the values in the equation to get the value of the constant.

2400 = 200 x 3 + c

c = 2400 - 600

c =1800

The equation for the linear variation of the population is,

p = 200t + 1800

Therefore, the linear equation for the variation of the population is p = 200t + 1800.

Statisticians prefer large samples. Describe briefly the effect of increasing the size of a sample (or the number of subjects in
Flauer [41]

Answer:

Margin of Error decreases

Pvalue decreases

Power increases

Step-by-step explanation:

The margin of error decreases as sample size increases given the same level of confidence, hence, the interval gets narrower.

The margin of error = (Zcritical * σ/√n) ; where, n is the denominator, as the denomination increases, the obtained value will decrease, hence, the margin of error.

When we have a false H0, then we expect a statistical result which will reject H0, with all facts remaining unchanged , increase in sample size n, will lead to decrease in Pvalue, because a lower P value increases the significance of statistical test needed to reject H0.

The power of a fixed level test when the null hypothesis is true, higher power is required to reject the null , increasing n will increase the probability of rejecting H0, by increasing the power of a fixed level test.
