It’s basically the same thing as -4=20 so your answer would be -5 or D
Answer:
The standard deviation reduces when sample size (n) increases
Step-by-step explanation:
From the above information given, we have that mean = 75.5
Standard deviation = 3.5
But Standard deviation = √summation (x-u)/n
This simply implies that when sample (n) is increased there would be a reduction in the standard deviate.
Janet = 7.55 x 15(hours) = 113.25
Kelsey = 15.10 x 15(hours) = 226.50
Ty = 13.85 x 15(hours) = 207.76
To gets Kelsey’s wage per hour you do 7.55 x 2 and to get ty you do 15.10(Kelsey’s wage per hour) - 1.25 which is 207.76
