Answer:
Yes, the test was conducted with a risk of a type I error.
Step-by-step explanation:
If we reject the null hypothesis, does this mean that we have proved it to be false beyond all doubt? Explain your answer.
Yes, for a null hypothesis to be rejected, it has being proven beyond all doubt that the null hypothesis will not work. the normal distribution has being used for the probability calculation.
if the null hypothesis is rejected and the alternative hypothesis is accepted, a type I error as occur.
In general terms:
‘a hypothesis has been rejected when it should have been accepted’. When this occurs, it is called a type I error.
Answer:
1.59C + 2.25A = 786.75
C + A = 33 (even if all were the higher paying adults, that would only be 33x2.25=74.25 far less than <<786.75)
1.59C + 1.59A = 33(1.59) = 52.47 subtract to eliminate C
(2.25-1.59)A = 786.75 -52.47 = 734.28
.66A = 734.28
A = 73428/66 = 1112.55 = about 1113 adults
C = 33-1113 = -1080 children
which makes no sense. over a thousand "negative" children? the public pool gave refunds to over a thousand prepaid children who didn't show up? but a public swimming pool, no matter how large, probably wouldn't accomodate 1113 adults.

Step-by-step explanation:
Answer:
a) Avg rate of change = 4 pounds per week
b) 160 pounds
Step-by-step explanation:
a)
The average rate of change is also called the slope. It is advertised that a person can loose 4 pounds in a week in the program. So, the average rate of change is 4 pounds per week.
Avg rate of change = 4 pounds per week
b)
In 5 weeks, a person can loose:
4 * 5 = 20 pounds (in 5 weeks)
Initially the person weighed 180 pounds, now after the program, he lost 20 pounds, so his weight will be:
180 - 20 = <u>160 pounds</u>
