If the sample size of population is 24 then the number of degrees of freedom for reading the t value is 23 which is option c.
Given sample size of 24,mean 23.
We have to determine the number of degrees of freedom which will be used to find the critical values of t.
Degree of freedom is the number of values in the final calculation of a statistic that are free to vary means that can change their values in the formula of calculating t.
t=(X-μ)/s/
where X is sample mean ,
μ is hypothsised population mean
s is sample standard deviation
n is sample size.
Degree of freedom=n-1
In this question n is 24 so the degree of freedom =24-1=23.
Hence the number of degrees of freedom for reading the t value is 23.

Answer:
The missing number is 4
Step-by-step explanation:
Given
21 x 39 x _____ x 19 divided by 12 = 5187
Required
Fill in the gap
Let the missing number be represented with y; So, the expression becomes
Multiply both sides by 12
Rearrange the expression on the left hand side
Divide both sides by 15561
Hence, the missing number is 4
