Answer:22x + 12
Step-by-step explanation:
To do that you'll need the mean and standard deviation of all the scores. Can you provide this info?
For example: Supposing that the mean of these scores were 52 and the standard deviation 3. You'd need to find the "z-score" of 57 in this case.
57 - 52
It is z = ------------ , or z = 5/3, or z = 1.67.
3
Find the area to the left of z = 1.67. Multiply that area by 100% to find the percentile rank of the score 57.
Hello!
To find the value of a digit, we must first look at its place value. When you're given a number, the place value of the number on the furthest right is 1, and for each number you move left, the place value increases by 10 times.
We're given the number 225,673. If we follow this rule, we see the place value of 3 is 1, 7 is 10, 6 is 100, and 5 is 1000.
Since we know that, we now know that there are 5 1,000s, which would make 5,000.
Therefore, your answer is 5,000.
Hope this helps!
It depends on which statistic test we wish to perform, the formula to find a degree of freedom could be different.
for Normal Distribution test, we do not need to find a degree of freedom
for T-test and Chi-Square test, we do n - 1 to find the degree of freedom, where 'n' is the sample size.
if we have two different sample size, then the degree of freedom is given by (n₁ + n₂) - 2
We are given only one sample size, n = 28, hence the degree of freedom is 28 - 1 = 27
