Answer:
Step-by-step explanation:
Given the mean is 3.2, standard deviation is 0.8 and the sample size is 64.
-We calculate the probability of a mean of 3.4 as follows:
#First determine the z-value:
#We then determine the corresponding probability on the z tables:
Hence, the probability of obtaining a sample mean this large or larger is 0.0228
The equation which is results from taking the square root of both sides of the provided equation is,
A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.
Let a number is <em>a. </em>Then this number in the form of square root can be written as,
The given algebraic equation in the problem is,
Take the square root, in both sides,
Cancel out the square root with the square of the number as,
Hence, the equation which is results from taking the square root of both sides of the provided equation is,

1) Write 3% as 3/100
2) Since, finding the fraction of a number is same as multiplying the fraction with the number, we have:
of 2500 =
× 2500
Therefore, the answer is 75
If you are using a calculator, simply enter 3÷100×2500 which will give you 75 as the answer.
Commission = $75
