Answer:

y = -\frac{1}{2} x - 4

Step-by-step explanation:

1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.

2. First, to find the slope, we can use the two points from the given line which are (-10,1) and (2,-5). Afterward, we plug in those values to this formula: \frac{y_2-y_1}{x_2-x_1}

  • \frac{-5-1}{2-(-10)}
  • \frac{-6}{12}
  • -\frac{1}{2}

3. Now that we have our slope, our equation will look like this so far: y = -\frac{1}{2} x + b

4. Since we're aware that b is the y-intercept, b = -4 because the line intersects the y-axis at (0,-4).

5. Now that we have the values of b and m, our equation will build up to this: y = -\frac{1}{2} x - 4

Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation i
Mnenie [13.5K]

Answer:

The population mean = sample mean = x`= 67.5

Population standard deviation = 13.369

Sample standard deviation= 4.225

Step-by-step explanation:

AS the population mean is not given we will calculate it from the sample.

The mean of the sampling distribution is equal to the population mean .

The sample mean is calculated by

x`= ∑x/n= 75,+ 62, +69,+65,+66,+64, +67,+70,+74 + 63/10

x`=675/10= 67.5

The standard deviation of the sample is equal to

u = σ/ √n   where σ is the population standard deviation and n is the number of observations.

Calculating the sample mean

s= √∑xi²/n- (∑x/n)²

s= √(45741/10)- (675/10)²

s= 4.2249

σ= u*√n= 4.229 *√10

σ=13.360
