Using it's concept, it is found that the probability that the special ball is chosen is given by:
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The total number of outcomes is given by the combination of k balls from the set of n balls, given by:
One ball is special, hence the probability the special ball is chosen is given by:

Answer:
Correct formula for a 99% confidence interval for the population mean =
Step-by-step explanation:
We are provided a simple random sample of 144 items of which sample mean, xbar = 1250.25 and Standard Deviation, s = 480.
We know that follows i.e.;
follows
So, 99% confidence interval is given by ;
P(-2.61138 < < 2.61138) = 0.99 {because at 143 degree of freedom t table
gives critical value of 2.61138 at 0.5% level}
Now, after further solving this we get,
99% confidence interval for the population mean =
Since, in the question options are not given so this must be the correct formula for calculating 99% confidence interval for the population mean.
Answer:
max weight truck can hold = 1200 pounds
your weight. 165 pounds
1200 - 165
1035 pounds left
3 pounds --- 1 brick
