Answer:
a level of significance of 0.01 = 1%
Step-by-step explanation:
given
Z = 0.0001
mean μ=0.21 g/mi
variate x= 0.21 + 0.03
standard deviation σ= 0.05 g/mi.
N = sample population 20 cars
z = (x −μ )/[σ /√N ]
Z =
Z = 0.03/ (0.05/√20) = 0.03/0.0111
Z = 2.63 +- 0.0001
Z= 2.6301 or 2.6299
checking the level of significance table from a statistical book gives
a level of significance of 0.01 = 1%
therefore the null hypothesis is accepted.
Answer:
The unit cost per ounce for turkey skylar is $ 0.316
Step-by-step explanation:
The total amount of sliced turkey = 5 pounds + 4 ounces
The total cost of turkey slice = $26.88
Now, as we know
1 pounds = 16 ounces
∴ 5 pounds = 16 × 5 = 80 ounces
So, the total amount is 5 pounds + 80 pounds = 85 pounds
∵ 85 pounds of turkey sliced cost $ 26.88
∴ 1 pounds of turkey sliced cost $ = $ 0.316
Hence the unit cost per ounce for turkey skylar is $ 0.316 Answer
