Answer:
Reject the null hypothesis.
Step-by-step explanation:
n1 = 16
n2 = 21
S.V1 = 5.8
S.V2 = 2.4
= 0.05
= Population Variance 1 ≤ Population Variance 2
= Population Variance 1 > Population Variance 2
Test statistic value = 5.8 / 2.4 = 2.417
Degrees of freedom is n - 1
15 and 20
Critical value is 
= 2.2
2.417 > 2.2
we reject the null hypothesis as the critical value is greater than the test statistic.

Step-by-step explanation:
Flat rate is the y- intercept b = 11.2
Charge per mile is the slope m = 3.1
<u>The equation is:</u>
I'm kind of thrown off for that negative sign, but I try it out in the one that makes sense is this one [ https://gyazo.com/192a76e70d2d46979691cabbf06e6c85 ] If you can better of explain where the negative sign will be great. Hope I helped.
Answer:
<em>$180.</em>
Step-by-step explanation:
First lets find the <em>interest rate.</em>
<em>6.1 ÷ 100 = 0.061</em>
<em>0.061 x $200 = 12.2</em>
based on the calculations, <em>12.2</em> is our interest rate <em>in a year</em>. Now lets find the interest rate in <em>15 years</em>.
<em>12.2 x 15 = $183 </em>
So <em>$183</em> is our<em> precise</em> interest rate in <em>15 years</em>, but lets<em> round the interest rate to the nearest 10 dollars.</em> Therefore, <em>$180 is our answer.</em>
