Answer:
1) True
2) True
3) False
4) True
5) True
Step-by-step explanation:
1) -2《3 - 3
-2《0
-2》-3 - 2
-2》-5
2) 4 > -3 + 3
4 > 0
4 > 1 + 2
4 > 3
3) -2《0 - 6
-2《-6 is false
4) 0 - 3 < 4
-3 < 4
0 + 3 > -1
3 > -1
5) 0 > -6 - 3
0 > -9
0 < 3 + 6
0 < 9
Answer:
The margin of error for a 95% confidence interval estimate for the population mean using the Student's t-distribution is of 6.22 ounces.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 23 - 1 = 22
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 22 degrees of freedom(y-axis) and a confidence level of
. So we have T = 2.0739
The margin of error is:
M = T*s
In which s is the standard deviation of the sample.
In this question:
s = 3.
Then
M = 2.0739*3 = 6.22
The margin of error for a 95% confidence interval estimate for the population mean using the Student's t-distribution is of 6.22 ounces.
Answer:
14.8 pounds
Step-by-step explanation:
Here, we want to get the actual value made of fat from the body weight
What we have to do here is to multiply the percentage by the body weight
Mathematically, we have this as;
18.8% of 127 pounds
= 18.8/100 * 127 = 14.80 pounds
