What is the slope of the line that passes through the points (6, -2)(6,−2) and (12, -2) ?(12,−2)? Write your answer in simplest
Lynna [10]

Slope of the line is 0

Step-by-step explanation:

  • Step 1: Given points are (6, -2) and (12, -2). Find the slope of the line using the formula m = (y2 - y1)/(x2 - x1) Here, y1 = -2, y2 = -2, x1 = 6 and x2 = 12

⇒ m = (-2 - -2)/(12 - 6) = 0/6 = 0

Commute times in the U.S. are heavily skewed to the right. We select a random sample of 500 people from the 2000 U.S. Census who
tresset_1 [31]

Answer:

<em>|t|  =  2.739 > 1.972 at 0.05 level of significance</em>

<em>Null hypothesis is rejected  at 0.05 level of significance</em>

<em>The researchers able to conclude from this data that the mean commute time in the U.S. is less than half an hour</em>

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

<u>Step(i)</u>:-

Given sample size n = 500

Given data

<em>mean of the sample x⁻ = 27.6 minutes</em>

<em>Standard deviation of the sample (S) =  19.6 minutes</em>

<em>Mean of the Population 'μ' = half an hour or 30 minutes</em>

<em>Level of significance ∝ =0.05</em>

t₀.₀₅ = 1.972

<u><em>Step(ii):</em></u>-

<u><em>Null hypothesis :H₀</em></u>: <em>μ= 30</em>

<u><em>Alternative Hypothesis :H₁:</em></u> <em>μ < 30</em>

Test statistic

    t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }

   t = \frac{27.6 -30}{\frac{19.6}{\sqrt{500} } }

 t = - 2.739

|t| = |-2.739| = 2.739

<u><em>Final answer</em></u>:-

<em>|t|  =  2.739 > 1.972 at 0.05 level of significance</em>

<em>Null hypothesis is rejected  at 0.05 level of significance</em>

<em>The researchers able to conclude from this data that the mean commute time in the U.S. is less than half an hour</em>
