For a data from population which is not normally distributed, the sample means would be approximately a normal distribution if the sample size (n) is greater than 30
Step-by-step explanation:
For a data from population which is not normally distributed, the sample means would be approximately a normal distribution if the sample size (n) is greater than 30 i.e n ≥ 30 this is because the shape of a sample distribution depends on the sample size. But for normal distribution population, the sample means would be approximately a normal distribution even if the sample size is less than 30;

Step-by-step explanation:
It would take Harley 46 minutes to arrive at work.
Step-by-step explanation:
Given,
Distance from house to work = 9.88 miles
Speed of bicycle = 13 mph
Distance = Speed*Time
Time = 
Time = 
Time = 0.76 hour
We know that 1 hour = 60 minutes
0.7 hours = 60*0.76
0.7 hours = 45.6 minutes
Rounding off to nearest whole minute
0.7 hour = 46 minutes
It would take Harley 46 minutes to arrive at work.
