In order to estimate the statistical difference between the average hourly wages of employees of two branches of a department store, two independent random samples were selected and the following statistics were calculated. Downtown Store North Mall Store Sample size 25 20 Sample mean $9 $8 Sample standard deviation $2 $1 A 95% interval estimate for the difference between the two population means is _____. Group of answer choices
Answer:
0.076 ; 1.924
Step-by-step explanation:
Given that :
_______Downtown Store ___ North Mall Store
n _______25 _______________20
Mean (m) _ $9 _______________$8
Sample sd_ $2 ______________$1
Standard Error (SE) = √[(s1²/n1) + (s2²/n2)]
√((2^2/25) + (1^2/20)) = 0.4582575
df = (25 + 20) - 2= 43
(m2 - m1) ± t(df = 43 , 0.025) * SE
(9 - 8) ± 2.01669 * 0.4583
(1 - 0.9242) ; (1 + 0.9242)
0.076 ; 1.924

Answer: 1) $0.76 per serving of pumpkin pie
2) 64 people
3)
1 1/3 cup sweet potatos
2 tablespoons + 2 teaspoons of white sugar
1 egg
1/4 teaspoon of salt
2 tablespoons of butter
2 tablespoons + 2 teaspoons of milk
1/4 teaspoon of vanillia
2 tablespoons + 2 teaspoons of brown sugar
1 tablespoon + 2 1/3 teaspoons flour
2 tablespoons + 2 teaspoons of peacans
Step-by-step explanation:
1) the total cost of the ingredients needed to prepare a pumpkin pie = $1.50 + ($2.59 / 6) + ($5.99 / 6) + $1.25 + ($3.79 / 2) = $6.075
if we cut 8 servings per pie, then the cost per serving = total cost of the pie/number of servings = $6.075 / 8 = $0.759375 ≈ $0.76 per serving of pumpkin pie
2) 1lb=16oz
24/6=4
4x16=64
Answer:
0.76 per serving of pumpkin pie
2) 64 people

Duff says that 10 times as many as 5 tens is 5 thousands. Is duff correct
Answer: My guess is hes incorrect, its 500 because we know 5 tens is 50 and if we make it ten times 50 it is 500
Answer:
No he’s not correct
Step-by-step explanation:
So he says that 10 times 5 tens is 5 thousands. 5 tens is 50. So if you do 10 times 50 it’s only 500 not 5 thousand. At least this is what I think you mean

Which expression is equivalent to 42 + 12? 7(6+5) 2(40+6) 6(7+2) 10(32+2)
Answer:
6(7+)
Step-by-step explanation:
1) Start by solving the original equation
42 + 12 = 54
2) Solve the other equations until you find a match
2a) Start with what's in the parenthesis
7(6+5) = 7(11) = 77
2b)
2(40+6) = 2(46) = 92
2c)
6(7+2) = 6(9) = 54
This is your answer
2d)
10(32+2) = 10(34) = 340
Answer: 6(7 +2)
Step-by-step explanation:
Calculate 42 + 12, which is 54.
Calculate 7(6 + 5), which is 7 * 11 = 77.
Calculate 2(40 + 6), which is 2 * 46 = 92.
Calculate 6(7 + 2), which is 6 * 9 = 54.
Calculate 10(32 + 2), which is 10 * 34 = 340.
And, we can conclude the expression 6(7 + 2) is equivalent to 42 + 12.
