Answer:
5
Step-by-step explanation:
The sample mean is given by dividing the standard deviation by the squareroot of SRS
Given standard deviation of 35 and SRS of 49, we know that the squareroot of 49 is 7 ie √49=7
By substituting the given values we can obtain the sample mean as follows.
sample mean=35/√49=35/7=5
The sample mean for the given question is hence 5
The answer is 9m.
Because 9 - 5 = 4 (difference) and (9)(5) = 45.
Done by trial and error.
Organize the numbers least to greatest
905,910,928,964,971,978,984,988,994,994
Find the middle number
905,910,928,964,971,978,984,988,994,994
971 and 978 are the middle numbers
Find average of the numbers 971 and 978
Median = 974.5
D is the correct answer
