A 2.09% increase.

This is just some simple multiplication. A 23% increase is the same as multiplying by 1.23, and a 17% decrease is like multiplying by 0.83, since 100-17=83. Just multiply 1.23*0.83, which equals 1.0209, or a 2.09% increase.

Answer: 2.09% increase

<u>Step-by-step explanation:</u>

Let x = the original amount. then

23% increase is: x(1 + 0.23) = 1.23x

and a 17% decrease is 1.23x(1 - 0.17)

                                   = 1.23x(0.83)

                                   = 1.0209x

x was the original amount and 1.0209x is the new amount.

The percent change is: \dfrac{new-original}{original}=\dfrac{1.0209x-x}{x}=\dfrac{0.0209x}{x}=0.0209

Since the result is positive, it represents an increase.

Move the decimal two places to the right to convert the number to percent.

+0.0209 = 2.09 increase

Rasek [7]

Answer:

Alan = reject H0

Bill = cannot say

Step-by-step explanation:

Given that Heather is a student in a class that has been asked to conduct a hypothesis test for a population proportion.

H0: p = 0.5 \\Ha: p ≠ 0.5

(two tailed test at 5% significance level)

Since she rejects null hypothesis p value should have been less than 0.05

when p value <0.05, it is definitely less than 0.10

So at 1% level of significance also the null hypothesis would be rejected.

So Alan also would get the same result as to reject the H0

But about Bill since Bill uses 0.01, we cannot definitely say that p value is less than or greater than 0.01

All we know is that p is less than 0.05

Hence it is impossible to tell from the information for Bill
