Answer: 110 square inches.
Step-by-step explanation:
The volume of a rectangular box would be:
In this case, we know the volume, the length and the height, and we don't know the width, so we're going to isolate it:
Substituting the data:
This width is also the width of the top of the box, so the area of the top would be:
Answer:
a) -1.25
b) 0.2112
c) -1.96
Step-by-step explanation:
Data provided in the question:
Sample size, n = 400
H0 : p = 20
= 175
Now,
a) The test statistic is given as:
Z =
on substituting the respective values, we get
Z =
= -1.25
b) The p-value = 2 × P(Z <-1.25)
Now from the standard normal table
P(Z <-1.25) = 10.56% = 0.1056
Thus,
p-value = 2 × 1056 = 0.2112
c) for a = 0.05,
the critical value is i.e
Now from standard normal table
= -1.96
