PolarNik [594]

Answer:

58,21 ≤ μ ≤ 61,79

Step-by-step explanation:

Normal Distribution

Poputation size n = 41

Population mean X = 60

Population standard deviation σ = 7

Question is: Confidence Interval 90 % ??

As Confidence Interval is 90 % then α = 10 %

And as we are dealing with a two tail test

α/2 = 0,05

We look in Z table for values for α/2 = 0,05 and find

z(α/2) = - 1,64 and z(α/2) = 1,64

Then

Confidence Interval is

X - Zα/2 * σ/√n ≤ μ ≤ X + Zα/2 * σ/√n

60 - ( 1,64 ) * 7/√41 ≤ μ ≤ 60 + ( 1,64 ) * 7/√41

60 - 1,64 * 1,09375 ≤ μ ≤ 60 + 1,64 * 1,09375

60 - 1,79375 ≤ μ ≤ 60 + 1,79375

58,21 ≤ μ ≤ 61,79

The total number of restaurant purchased meals that the average person will eat in a restaurant, and a car, or at home in a year

Andrei [34K]

Answer:

80 restaurant purchased meals are eaten in a restaurant

31 meals are eaten in a car

60 meals are eaten at home

Step-by-step explanation:

Let us suppose r be the total number of meals eaten in a restaurant

Let us suppose c be the total number of meals eaten in a car

Let us suppose h be the total number of meals eaten in a home

The total number of meals eaten in a restaurant, in a car or at home is given as 163. Hence, $r + c + h = 171.....[A]$
The total number meals eaten in a car or at home exceeds the number eaten in a restaurant by 11. Hence, $c + h = r + 11.....[B]$
Twenty more restaurant-purchased meals will be eaten in a restaurant than at home. Hence, $r = h + 20.....[C]$
