A sample of five measurements, randomly selected from a normally distributed population, resulted in the following summary stati
stics: x = 4.8,s = 1.3 Test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, mu < 6. use alpha =.05. Test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, mu 6. Use alpha =.05 Find the observed significance level for each test.

Answer:
y - 4 = (x - 7)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (7, 4)
m = =
Use either of the 2 points for (a, b)
Using (7, 4), then
y - 4 = (x - 7) ← in point- slope form
