Answer:
The correct option is a) True
Step-by-step explanation:
Consider the provided statement.
A 90% confidence interval for a population parameter means that if a large number of confidence intervals were constructed from repeated samples, then on average, 90% of these intervals would contain the true parameter
First understand what is 90% confidence interval.
The level of confidence describes the uncertainty associated with a method of sampling.
A confidence level of 90 percent means that we would expect the population parameter to be included in 90 percent of the interval estimates.
From the above definition of confidence level we can concluded that the provided statement is true.
Hence, The correct option is a) True
Answer:
EH = 3.31
Step-by-step explanation:
We have been given a right angle triangle EKL. As KH has been given as the altitude (perpendicular) of the right angled triangle, and K is the right angle, we can say that EK is tthe base of the triangle and EH is the only side lleft, which is the hypotenuse of the triangle.
Where,
EK = Base = 3
KH = perpendicular altitude
EH = Hypotenuse
m<K = 90
m<E = 25
We know that
cosθ = Base/ Hypotenuse
cos 25 = 3/ EH
EH = 3/cos25
EH = 3.31
Perpendicular alitutude can also be calculated by using the formula for tanθ.
