Money Required for making 1 Sandwich that is Cost Price of 1 Sandwich = S Dollar
Selling Price of 1 Sandwich = 20 % more than Cost Price S
= S + 20 % of S
=
=$ 1.20 S
= $(S + 0.20 S)
Selling Price of 73 Sandwiches = $ 73 (S + 0.20 S)
The expression $73(S+0.2 S) →→ Selling Price of 73 Sandwiches
Answer:
P-value = 0.02275
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 12 kilograms
Sample mean, = 11.5 kilograms
Sample size, n = 4
Alpha, α = 0.05
Population standard deviation, σ = 0.5 kilograms
First, we design the null and the alternate hypothesis
We use one-tailed(left) z test to perform this hypothesis.
Formula:
Putting all the values, we have
We calculate the p-value from the standard z-table:
P-value = 0.02275
