Step-by-step explanation:
To find k, calculate the ratio of corresponding sides, image to original, that is
k = =
=
Thus
QR' = × QR =

Answer:
We can approximate to normal.
The parameters of the approximate normal distribution are:
It is not unusual to have 23 or more successes. The probabiltity of this event happening is 13.4%.
Step-by-step explanation:
To approximate the binomial distribution to a normal distribution, we can calculate n*p and n*q and if both are bigger than 5 we can do the approximation.
We can approximate to normal.
The parameters of the approximate normal distribution are:
The continuity correction factor is used because the binomial is a discrete function and the normal a continous function.
The probability of 23 successes must be expressed in the normal distribution as:
It is not unusual to have 23 or more successes. The probabiltity of this event happening is 13.4%.
