Answer:
= ( -4.725, 6.945) pg/ml
Therefore at 95% confidence interval (a,b) = ( -4.725, 6.945) pg/ml
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 gain x = 1.11 pg/ml
Standard deviation r = 15.18 pg/ml
Number of samples n = 26
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
1.11+/-1.96(15.18/√26)
1.11+/-1.96(2.977042931397)
1.11+/-5.835004145539
1.11+/-5.835
= ( -4.725, 6.945) pg/ml
Therefore at 95% confidence interval (a,b) = ( -4.725, 6.945) pg/ml
Answer: The correct answer is $85.56
Step-by-step explanation:
If Karen gets 23.5 miles per one gallon of gas, we divide 582.8 miles by 23.5 to see how many gallons she will use to go the 582.8 miles. The answer is 24.8 gallons. (582.8/23.5=24.8)
We then multiply 24.8 ( the total amount of gallons) x $3.45 (per gallon)= $85.56 for the entire trip
Answer:

180⁰-77 = 103⁰
Answer:
a = 12 ft, b = 12 ft
Step-by-step explanation:
The triangle is 45 45 90 right triangle
so a = b
Ratio of leg : hypo. = a : a√2
Given hypo = 12√2, so legs a = b = 12
Answer
a = 12 ft, b = 12 ft
