A study on students drinking habits asks a random sample of 60 male UF students how many alcoholic beverages they have consumed

in the past week. The sample reveals an average of 5.84 alcoholic drinks, with a standard deviation of 4.98. Construct a 95% confidence interval for the true average number of alcoholic drinks all UF male students have in a one week period.

Answer:

A. (4.78, 6.90)

Step-by-step explanation:

Using the following formulas the lower and upper limits of the Interval are calculated

Lower limit = mean - (standard deviation /√sample size)* Zr

Upper limit = mean + (standard deviation /√sample size)* Zr

Zr depends on confidence interval  and can be found in a z table

Zr for 90% = 1.645

then

Lower limit = 5.84 - (4.98 /√60)* 1.645 = 4.78

Upper limit = 5.84 + (4.98 /√60)* 1.645 = 6.90

We are first ask to translate this equation. So using the correct notation...

3X-9=6x6/4

We can also solve it.

3x-9 = 6x6/4

3x-9 = 36/4

3x-9 = 9

3x = 18

x=6

answer: X=6

This problem is a multi step problem. All you have to do is break it down into parts to make it easier. We can start by finding the diameter of the inner circle. 

1. circumference = πd   (Since the circumference is given as 44, and we know to use 22/7 for π, divide 44 by 22/7 to get d.) 
         44 / 22/7 = about 14.0 when rounded

2. Now add +8 to the 14 since we know that there are 4 ft. on both sides of the small inner circle. 
         14 + 8 = 22

3) The last step gave us the diameter of the bigger outer circle. Now, we have to plug in the 22 for d in the formula for circumference to find the circumference of the outer circle. 
         c = πd  →  c = 22 * 22/7 = 484/7 (484/7 = about 69 when rounded as a decimal)

4) The last step now is to subtract the circumferences, since the problem was asking for how much greater the outer circle's circumference is than the inner circle. 
       69 - 44 = 25

Your answer should be about 25 ft.

********** Note the answer they are looking for may be slightly different depending on whether they were looking for a fraction or decimal answer and where they rounded. ********************************************************
