A professor of statistics wants to test that the average amount of money a typical college student spends per day during spring
STALIN [3.7K]

Answer:

Option c: Fail to reject the null hypothesis at α = 0.10

Step-by-step explanation:

We are given;

Population mean; μ = 70

population standard deviation; σ = 17.32

Sample mean; x¯ = 72.43

Sample size; n = 35

Thus;

Null hypothesis; H0: μ = 70

Alternative hypothesis; Ha: μ > 70

Z-score formula is;

z = (x¯ - μ)/(σ/√n)

z = (72.43 - 70)/(17.32/√35)

z = 2.43/2.9276

z = 0.83

From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.05 and one tailed hypothesis, we have;

P-value ≈ 0.2033

It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.05

Similarly, From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.01 and one tailed hypothesis, we have;

P-value ≈ 0.2033

It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.01

Similarly, From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.10 and one tailed hypothesis, we have;

P-value ≈ 0.2033

It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.10

From the 3 significance values, the correct option is option c. fail to reject the null hypothesis at α = 0.10

I need with these problems
ch4aika [34]

Answer:

1. \frac{5}{6}

3. \frac{7}{0} (undefined slope)

5. -\frac{7}{4}

7. 24

Step-by-step explanation:

slope (m)

rate of change (r)

1. m = \frac{y_2-y_1}{x_2-x_1}=\frac{8-3}{13-7} =\frac{5}{6}

3. m = \frac{y_2-y_1}{x_2-x_1}=\frac{4-(-3)}{9-9} =\frac{7}{0} (undefined slope)

5. m = \frac{y_2-y_1}{x_2-x_1}=\frac{-1-6}{0-(-4)} =\frac{-7}{4}=-\frac{7}{4}

7. r = \frac{f(b)-f(a)}{b-a}=\frac{24-0}{1-0}=\frac{24}{1}=24

Hope this helps!

What’s this answer for algebra 2
Digiron [165]

Answer:

Step-by-step explanation:

5x - 3y = 6 | 6x - 4y = 2

Multiply the first equation by -6, and the second one by 5:

-30x + 18y = -36 | 30x - 20y = 10

Add them together:

-2y = -26

2y = 26

y = 13

Use which equation you please to solve for x:

5x - 3y = 6

5x - 3(13) = 6

5x - 39 = 6

5x = 45

x = 9

(9, 13)
