Answer:
So, the confidence interval is [34.08, 38.72].
Step-by-step explanation:
We know that a random sample of 18 fields of barley has a mean yield of 36.4 bushels per acre and standard deviation of 7.37 bushels per acre.
We have :
We use the Appendix: Critical Values Tables, and we get that:
We calculate the margin of error:
We get the boundaries of the confidence interval:
So, the confidence interval is [34.08, 38.72].

Step-by-step explanation:
Answer: 5x(x-1)
Step-by-step explanation:
2(x2 - x) + 3 (x2 - x)
5x(2 power) - 5x
= 5x(x - 1)
OK. Instead of trying to find a quick, slick, easy, short way,
let's just do it the long, sensible way. We'll find the value of
each function at x=-2 and at x=-4, then see which one changed
the most and which one changed the least.
g(x) . . . (table)
when x=-2 . . . g(x) = 0
when x=-4 . . . g(x) = -8
Amount of change . . . 8
h(x) = |2x + 3| + 7
h(-2) = |-4+3| + 7 = 1+7 = 8
h(-4) = |-8+3| + 7 = 5+7 = 12
Amount of change . . . . . . . 4
m(x) . . . (graph)
m(-2) . . . . . -10
m(-4) . . . . . less than -18
maybe -20 or -25
Amount of change . . . more than 8
maybe 10 or 15
Largest change . . . m(x)
Smallest change . . h(x)
