### A random sample of 125 students is chosen from a population of 4,000 students. If the mean IQ in the sample is 100 with a standard deviation of 8, what is the 98% confidence interval for the students' mean IQ score?

Answer: 98.33 - 101.67

Step-by-step explanation:

The given Sample mean n= 100

Standard deviation

Mean IQ in the sample

Standard error of mean =

Standard error of mean =

Thus, standard error =

Standard error of mean (SE)= 0.7155

We know that  z - score for 98% confidence interval is 2.33 .

Now, 98% confidence interval will be

n-z(SE) and n+z(SE)

Hence, the 98% confidence interval for the students' mean IQ score will be 98.33 - 101.67

### How can you quickly calculate 20 percent of any bill amount?

First, convert the percent into a decimal. To do this, simply more the % sign two places to the left and make it into a decimal point.

20% = 0.20

Then we will let x be our bill amount.

Then multiply 0.20 and x together to get your answer.

So, 0.20 * x is your answer.

### In a roller-skating rink, the skaters all move at different speeds. Most skate slightly faster or slower than others, but sometimes an adventuresome skater accelerates to an "outlying" speed that is much higher than that of everyone else, causing a hazard. As a result, skating rinks often post a sign that says:Any skater moving faster than the average speed of all the skaters will be asked to leave the rink.It is clear what the sign means, but it is statistically nonsensical. If there are 150 skaters in the rink, all skating at slightly varying speeds, what is the best estimate for how many of them are moving faster than the average speed of all the skaters? A. 100 B. 0 C. 25 D. 75 E. 50

Take y=mx+b
let x=years and
y=lost money

then divide 1824 by 12 = 152
and since it is a loss make it into -152
and insert it for m as the constant rate of loss per month
your answer should be y=-152x.
if the store has a starting amount of money plug that into b.

### Nigel and Mia are searching for a treasure chest under water. The straight line distance between them is 100 meters. Given the angles in the diagram, who is closer to the treasure chest and why? a) Nigel is closer because his distance to the chest is opposite the larger angle. b) Mia is closer because her distance to the chest is opposite the smaller angle. c) Nigel is closer because his distance from the chest is 100 meters. d) Mia is closer because her distance from the chest is 100 meters.

The answer is b) Mia is closer because her distance to the chest is opposite the smaller angle.

In the relationship of triangle sides and its angles, the shortest side will always be opposite to the smallest interior angle. Furthermore, the largest side will always be opposite to the largest interior angle. Since Mia's distance to the treasure chest is opposite to the smaller angle 65
°, then she is much closer to the chest.
