Answer:
12%
Step-by-step explanation:
So 5.5 to 5.62 is .12
Then calculate the difference of 5.5 *.12=0.66
Then do “0.66 is what percent of 5.5?”
The answer is 12%
Thank you for reading, and mark this brainliest
8x+6=54
subtract 6 from both sides
8x+6-6=54-6
8x=48
x=6
Answer:
Confidence interval is 0.7 ≤ p ≤ 0.8
The margin of error is 7.1 %
Step-by-step explanation:
We have to calculate a 98% confidence interval for the proportion.
The sample proportion is p=0.75.
The standard error of the proportion is:
Here we have, the proportion or point estimate given by
= 150/200 = 0.75
Sample size, n = 200
The formula for confidence interval, CI, given a proportion, is;
At 98% z = ±2.326348
Plugging in the values of, , z and n we get;
CI = 0.6787704 ≤ p ≤ 0.8212296
To one decimal place, we have
CI = 0.7 ≤ p ≤ 0.8
There are different data sets that have the same mean, median, and mode. Here's the data sets i got:
Set 1: 2,2,2,3,5,5
Set 2: 0,1,2,2,4,10
The mean for the 1st set is:
2+2+2+3+5+5= 19/6=3.1
The mean for the 2nd set is:
0+1+2+2+4+10= 19/6=3.1
The median for the 1st and 2nd set is:
2.5
And the mode (most common number) for the 2 sets is:
2
Hope this helps!! :-)
Sorry if I took to long, it took me awhile to come up with 2 sets that had different numbers, but had the same mean/median/ and mode.
Answer:
1/4 - 1/8 = 2/8 - 1/8 = 1/8
