Answer:$6.11 per bag
Step-by-step explanation: The total of both the apples and ice cream is 55.68. Since we’re just trying to find the total price of apples, we’ll subtract the total price of ice cream. 55.68-6.80=48.88. Now we’ll divide $48.88 by 8, since there are 8 bags. That leaves us with $6.11
Answer:
(115.2642, 222.7358).
Step-by-step explanation:
Given data:
type A: n_1=60, xbar_1=1827, s_1=168
type B: n_2=180, xbar_2=1658, s_2=225
n_1 = sample size 1, n_2= sample size 2
xbar_1, xbar_2 are mean life of sample 1 and 2 respectively. Similarly, s_1 and s_2 are standard deviation of 1,2.
a=0.05, |Z(0.025)|=1.96 (from the standard normal table)
So 95% CI is
(xbar_1 -xbar_2) ± Z×√[s1^2/n1 + s2^2/n2]
=(1827-1658) ± 1.96×sqrt(168^2/60 + 225^2/180)
= (115.2642, 222.7358).
