the following set of data relates mean word length and reccomended age level for a set of childrens books

reccomended age level ~ mean word length

4~3.5

6~5.5

5~4.6

6~5.0

7~5.2

9~6.5

8~6.1

5~4.9

A) create a scatterplot and classify the linear correlation

b) determine correlation coeffitient

c) determine th eline of best fit

d) use model to predict the average word length in a book reccomended for 12 year olds

the manager of a restaurant looks at the reciepts for the past two days the following table shows the range of values

amount of reciepts frequency of reciepts

0 - 0.99 ~ 17

1- 1.99 ~ 85

2- 2.99 ~ 140

3- 3.99 ~ 75

4- 4.99 ~ 82

5- 5.99 ~ 73

6- 6.99 ~ 62

7- 7.99 ~ 21

8- 8.99~ 14

9- 9.99 ~ 22

10 - 15 ~ 43

find a) D2 b)P87 and c) standard deviation

a die is thrown 20 times and a success is defined as one or a six on the upface of the die.

a) use the binomial distribution to determine the probability of getting exactly five successes on the 20 trials

b) Use the normal approximation to the binomial to answer the same question that is the probability of getting exactly five successes in the 20 trials

Eldon recieved 72 on his first calculas test. The marks were normally distributed with a mean of 60 and a standard deviation of 8. He recieved 80 on the next test, which which was normally distributed with a mean of 75 and a standard deviation of 6. Which was the better mark, relatively speaking

on a standard IQ test the scores are normally distributed with a mean of 100 and a standard deviation of 20.

a) if you score 140 in what percentile are you?

b) if you score 90 in what percentile are you

so i was given a table of data which looked like this kinda;

amount of reciept ~ frequency of reciepts

0- 0.99 ~ 17

1.00 - 1.99 ~ 85

2.00 - 2.99 ~ 140

3.00- 3.99 ~ 75

4.00 - 4.99 ~ 82

5.00 - 5.99 `~ 73

6.00 - 6.99 ~ 62

7.00 - 7.99 ~ 21

8.00 - 8.99 ~ 14

9.00 - 9.99 ~ 22

10.00 - 15.00 ~ 43

ok with that data i need to find a) Q3 b) D2 c) P87 and d) the standard deviation
