Answer: = ( 0.0384, 0.1216)
Therefore at 95% confidence interval the difference between teenage female and male depression rates is between ( 0.0384, 0.1216)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 0.08
Standard deviation r = 0.03
Number of samples n = 2
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
0.08+/-1.96(0.03/√2)
0.08+/-1.96(0.021213203435)
0.08+/-0.0416
= ( 0.0384, 0.1216)
Therefore at 95% confidence interval= ( 0.0384, 0.1216)
Answer:
385 miles
Step-by-step explanation:
since Patel drove 165 miles in 3 hours, we can divide the 2 to find the miles per hour.
165mi/3 hr = 55 mph
we can multiply this number by 7 to see how many miles Patel will travel going this speed.
55 mph × 7hr = 385 miles
