Answer: t _(α/2) = 2.060
Step-by-step explanation:
Given that;
sample size n = 26
confidence interval = 95%
level of significance α = ( 1 - 95/100 ) = 0.05
but from the question the salaries (26) are use to estimate the mean of the population so, its a two tail test
therefore our level if significance α will be divided by 2 = 0.05/2 = 0.025
now our degree of freedom df = 26 - 1 = 25
FROM standard t-table value
the critical value of t for the level of significance 0.025
and 25 degree of freedom is 2.060
therefore, t _(α/2) = 2.060
You’re close already :).
Slope is rise/run!
So, here you’ve showed that the rise is up 3 units
You’ve also showed that you move over to the right 2 units
It will be 3/2
Area rectangle: L * W
5 * 9
Area triangle: (1/2) * b * h
(1/2) * 3 * 4
Rectangle = 45
Triangle = 6
45 + 6 = 51 cm^2
Here’s a picture if the formula. M is slope. X1 and Y1 are one coordinate and X2 and Y2 are the other.
Answer:
wait what are we measuring I would need to see the graph to know
