A survey of 90 men found that an average amount spent on St. Patrick's day of $55 with a standard deviation of $18. A similar su

dem82 [27]

Answer:

The value of the test statistic is 4.70.

Step-by-step explanation:

The hypothesis for this test can be defined as follows:

<em>H</em>₀: Men do not spend more than women on St. Patrick's day, i.e. μ₁ = μ₂.

<em>H</em>ₐ: Men spend more than women on St. Patrick's day, i.e. μ₁ > μ₂.

The population standard deviations are not known.

So a <em>t</em>-distribution will be used to perform the test.

The test statistic for the test of difference between mean is:

$t=\frac{\bar x_{1}-\bar x_{2}}{\sqrt{\frac{s^{2}_{1}}{n_{1}}+\frac{s^{2}_{2}}{n_{2}}} }$

Given:

$\bar x_{1}=55\\s_{1}=18\\n_{1}=90\\\bar x_{1}=44\\s_{1}=16\\n_{1}=86$

Compute the value of the test statistic as follows:

$t=\frac{\bar x_{1}-\bar x_{2}}{\sqrt{\frac{s^{2}_{1}}{n_{1}}+\frac{s^{2}_{2}}{n_{2}}} }=\frac{55-44}{\sqrt{\frac{15^{2}}{90}+\frac{16^{2}}{86} }}=4.70$

Thus, the value of the test statistic is 4.70.

PLZ SOLVE ASAP Solve for f. -11f=7(1-2f)+5

viktelen [127]

Answer:

f = 4

Step-by-step explanation:

Step 1: Distribute

-11f = 7 - 14f + 5

Step 2: Combine like terms

-11f = 12 - 14f

Step 3: Add 14f to both sides

3f = 12

Step 4: Divide both sides by 3

f = 4

Write the following in the ratio form a) 0.5 b) 0.6 c) 1.25 d) 3.4

alex41 [277]

Answer:

A) 1:2

B) 3:5

C) 5:4

D) 17:5

Step-by-step explanation:

Step 1) Convert the decimal number to a fraction

Step 2) Multiply the numerator and denominator by 10 to eliminate the decimal point.

Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF)

Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon

Heres an example. I'll do the last one.

3.4 = 3.4/1

(3.4 x10) /(1 x 10)= 34/10

34 /2 = 17

10/2 = 5

17/5 = 17:5
