Answer:
We conclude that cheddar popcorn weighed less than 5.5 ounces.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ =5.5 ounces
Sample mean, = 5.23 ounces
Sample size, n = 64
Alpha, α = 0.05
Sample standard deviation, σ = 0.24 ounce.
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, we conclude that cheddar popcorn weighed less than 5.5 ounces.
You will distribute the negative sign inside the parenthesis, so the whole thing simply to t-8-t+15, and if you combine like term you get 7
The arc length by definition is given by:
S = R * Theta
Where,
R: radio
Theta: central angle
Substituting values we have:
S = (5.8) * (5.4)
S = 31.32 inches
Answer:
The value of s, the arc length (measured in inches) is:
S = 31.32 inches
Weight of 25,000 bricks = 30,000
Weight of each brick = 30,000/25,000 = 1.2 pound
