What is the slope of the following graph? (write your answer as a fraction unless divided by 1. Do not use spaces in your answer
alexira [117]

The slope of the graph is 4/5

<h3>How to determine the slope</h3>

Using the formula

Slope = Δ y-axis / Δ x- axis

y2 = -4

y1 = 0

x2 = -5

x1 = 0

Slope = \frac{y2 - y1}{x2 - x1}

Substitute the values into the formula

<em>Slope = </em>\frac{-4 - 0}{- 5 - 0}

Slope = \frac{-4}{-5}

Slope = \frac{4}{5}

Therefore, the slope of the graph is 4/5

Determine if the following statements are true or false, and explain your reasoning. If false, state how it could be corrected.
goblinko [34]

Answer:

a. True

b. False

c. False

d. True

e. True

Step-by-step explanation:

a.

True,

A 99% confidence interval covers more than a 95% confidence interval.

This is because, more potential values must be allowed within the interval, to be more confident that the true population value falls within the interval

b.

False,

Decreasing the significance level will decrease the probability of making a type 1 error because the probability of a Type I error is the same as α.

c.

False,

The evidence is not sufficient to make a conclusion that µ = 5.

d. True

The probability of making a type II error (failing to reject the null hypothesis when it is actually false) is called β (beta).

The probability of not making this error is 1 - β

1 - β + β = 1

e.

True,

Large sample sizes can decrease the margin of error.

Because the relationship between margin of error and sample size is simple is that when the sample size increases, the margin of error decreases and vice versa
