Step-by-step explanation:
Answer:
g = 3
Step-by-step explanation:
miles / gallon = miles / gallon
104 / 4 = 78 / g
cross-multiply to solve for 'g':
78(4) = 104g
312 = 104g
312/104 = g
3 = g

ALL TOGETHER there is 24 donuts.
take half of 24, or 24 divided by 2, and you get 12.
so we know 12 of the donuts are vanilla with sprinkles.
then 2 had strawberry frosting and the rest had chocolate and sprinkles.
we took 12 away so we only have twelve left and if 2 of those 12 are strawberry with no sprinkles and the rest are chocolate WITH sprinkles, this means 10 are chocolate with sprinkles.
so 10 chocolate and sprinkles +12 vanilla and sprinkles=22 donuts with sprinkles out of 24 donuts total
Answer: Choice B
There is not convincing evidence because the interval contains 0.
========================================================
Explanation:
The confidence interval is (-0.29, 0.09)
This is the same as writing -0.29 < p1-p1 < 0.09
The thing we're trying to estimate (p1-p2) is between -0.29 and 0.09
Because 0 is in this interval, it is possible that p1-p1 = 0 which leads to p1 = p2.
Therefore, it is possible that the population proportions are the same.
The question asks " is there convincing evidence of a difference in the true proportions", so the answer to this is "no, there isn't convincing evidence". We would need both endpoints of the confidence interval to either be positive together, or be negative together, for us to have convincing evidence that the population proportions are different.
