Answer:
Option 2) Null hypothesis: p = 0.078
, Alternate hypothesis: p > 0.078
Step-by-step explanation:
We are given the following in the question:
According to the National Center of Health Statistics, about 7.8% of all babies born in the U.S. are categorized as low birth weight.
Sample size, n = 1200
p = 7.8% = 0.078
We have to carry a hypothesis test whether national percentage is higher than 7.8% or not.
Thus, we can design the null and the alternate hypothesis
Thus, the correct answer is:
Option 2) Null hypothesis: p = 0.078
, Alternate hypothesis: p > 0.078
I believe it's always a parallelogram??
It would be = because they shipped the same amount in each year
Answer:
148cm^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is 2(hl)+2(hw)+2(wl).
we just plug in the values.
2(6 x 5) + 2(6 x 4) + 2(4 x 5)
= 2(30) + 2(24) + 2(20) then simplify
= 60 + 48 + 40
= 148
It would take 4.44 minutes to fill the sink using both faucets P and faucet Q together
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let t represent the time it takes to fill the sink using both faucets together, hence:
(1/10 + 1/8)t = 1
t = 4.44 minutes
It would take 4.44 minutes to fill the sink using both faucets P and faucet Q together
