Step-by-step explanation:
The formula to find the t-test statistic for differences between in two population mean:-
,where = sample mean difference
SE= Sample error
Given : SE= 4 points
t-statistic = 2.00
Substitute theses values in the above formula , we get
Hence, the sample mean difference is
Answer:
x y
2 8
3 12
5 60
7 28
Step-by-step explanation:
5 x 12 = 60
Let c represent the weight of cashews and p the weight of pecans.
Then c + 10 = total weight of the nut mixture.
An equation for the value of the mixture follows:
$1.50(10 lb) + $0.75c = (c+10)($1.00)
Solve this equation for c: 15 + .75c = c + 10. Subtract .75c from both sides:
15 = 1c - 0.75c + 10. Then 5=0.25c, and c = 5/0.25, or 20.
Need 20 lb of cashews.
Check: the pecans weigh 10 lb and are worth $1.50 per lb, so the total value of the pecans is $15. The total value of the cashews is (20 lb)($0.75/lb), or $15. Does (20 lb + 10 lb)($1/lb) = $15 + $15? Yes. So c= 20 lb is correct.
