23. To find out whether Chris, Mary Beth, and Allison are in agreement with each other, we just need to find out what the percentage is that we are working on and use what we know to understand if they are in agreement.

Chris says that 46.2% of the votes went to a certain candidate. A percent is the fraction of parts-to-whole represented in a decimal form. A percentage is NOT in decimal form, however. To get a percentage in decimal form, you can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.

46.2% = 0.462

Based on this, we can see that at least Chris and Allison are in agreement, since Allison said that 0.462 voters voted for the candidate in question.

To find out if Mary Beth stands with them, we just have to divide the amount of people who she says voted for the candidate by the amount of voters in total to get her percentage.

231 / 500 = 0.462

This matches the other two's results, so we can safely come to our conclusion.
YES, Chris, Mary Beth, and Allison are in agreement on the population of voters who voted for the candidate.
Hope that helped! =)

A bag of chips states that it contains 24 oz of chips. A sample of 40 bags finds a mean of 23.7 and a standard deviation of 0.2.

PIT_PIT [208]

Answer:

a) Null hypothesis: $\mu \geq 24$

b) Alternative hypothesis: $\mu < 40$

c) $t=\frac{23.7-24}{\frac{0.2}{\sqrt{40}}}=-9.487$

d) $df=n-1=40-1=39$

$p_v =P(t_{39}$

e) Since the p value is almost 0 we have enough evidence to reject the null hypothesis at the significance level of 0.05

f) Since we reject the null hypothesis we have enough evidence to conclude the true mean is significantly less than 24 ounces

Step-by-step explanation:

Information provided

$\bar X=23.7$ represent the sample mean for the weigth in ounces

$s=0.2$ represent the standard deviation

$n=40$ sample size

$\mu_o =24$ represent the value to verify

$\alpha=0.05$ represent the significance level

t would represent the statistic

$p_v$ represent the p value

Part a

For this case the null hypothesis is:

Null hypothesis: $\mu \geq 24$

Part b

And the alternative would be given by the claim:

Alternative hypothesis: $\mu < 40$

Part c

We don't know the population deviation so then the statistic would be given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

And replacing the data given we got:

$t=\frac{23.7-24}{\frac{0.2}{\sqrt{40}}}=-9.487$

Part d

The degrees of freedom are given by:

$df=n-1=40-1=39$

And the p value for this case would be:

$p_v =P(t_{39}$

Part e

Since the p value is almost 0 we have enough evidence to reject the null hypothesis at the significance level of 0.05

Part f

Since we reject the null hypothesis we have enough evidence to conclude the true mean is significantly less than 24 ounces

Answer:

Step-by-step explanation:

+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5

−(−) 6−(−3) = 6 + 3 = 9

+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5

−(+) 8−(+2) = 8 − 2 = 6
