Answer:
36
Step-by-step explanation:
Data provided in the question:
Standard error = 1.5 minutes ( ∵ number are repetitive 1.51.5 )
Standard deviation = 9 minutes ( ∵ number are repetitive 99 )
Now,
Standard error = ( Standard deviation ) ÷ √n
Here,
n is the sample size
Therefore,
on substituting the respective values, we get
1.5 = 9 ÷ √n
or
√n = 9 ÷ 1.5
or
√n = 6
or
n = 6² = 36
