If the rejection region is +1.10, what will be your decision if the z computed value is 2.34

IRINA_888 [86]

The decision when the z value is within the rejection region is that we'll have to reject the null hypothesis.

<h3>What is a rejection region?</h3>

It should be noted that the rejection region is also known as the critical region. It is the set of values where the null hypothesis is rejected.

When the observed test statistic is in the rejection region, we'll have to reject the null hypothesis and then accept rte alternative hypothesis.

Answer:

4. True

5. False

Step-by-step explanation:

4. The number of x-intercepts produced by the quadratic formula may be 0, 1, or 2. It will be 0 if the two roots are complex. It will be 1 if the two roots lie in the same place (one root with multiplicity 2). It is true that there may be only one x-intercept.

__

5. The value of 'b' in the quadratic formula is the coefficient of the linear term. In the given quadratic, it is -5, not 5.

Which graph represents the following system of inequalities?<br> y > 2x - 5<br> y <-3x

NARA [144]

Answer:

The graph i the attached figure

Step-by-step explanation:

we have

$y > 2x-5$ ----> inequality A

The solution of the inequality A is the shaded area above the dotted line $y=2x-5$

The slope of the dotted line is positive

The x- intercept of the dotted line is the point (2.5,0)

The y- intercept of the dotted line is the point (0,-5)

$y < -3x$ -----> inequality B

The solution of the inequality B is the shaded area below the dotted line $y=-3x$

The slope of the dotted line is negative

The x- intercept of the dotted line is the point (0,0)

The y- intercept of the dotted line is the point (0,0)

The solution of the system of inequalities is the shaded area between the two dotted lines

see the attached figure
