Find the critical value t a/2 needed to construct a confidence interval of the given level with the given sample size. level 95%

stepan [7]

Α = 1- (95/100) = 1-0.95 = 0.05

p = 1- α/2 = 1- 0.05/2 = 1-0.025 = 0.975

Degrees of freedom, df = Sample size -1 = 11-1 = 10

From t-tables, with cumulative probability pf 0.975 and df of 10,
Critical value = 2.228

Write the standard form of the equation of the line through the given points.

fenix001 [56]

You first have to find the slope using the slope formula. That looks like this with our values: $\frac{-2-(-1)}{5-(-3)}=- \frac{1}{8}$ . So the slope is -1/8. Use one of the points to first write the equation in y = mx + b form. We have an x and a y to use from one of the points and we also have the slope we just found. Filling in accordingly to solve for b gives us $-2=5(- \frac{1}{8})+b$ and $-2=- \frac{5}{8}+b$ . Adding 5/8 to both sides and getting a common denominator gives us that $b=- \frac{11}{8}$ . Writing our slope-intercept form we have $y=- \frac{1}{8}x- \frac{11}{8}$ . Standard form for a line is Ax + By = C...no fractions allowed. So let's get rid of that 8 by multiplying each term by 8 to get 8y = -x - 11. Add x to both sides to get it into the correct form: x + 8y = -11
