The overhead reach distances of adult females are normally distributed with a mean of 197.5 cm and a standard deviation of 8.6 cm.
a. find the probability that an individual distance is greater than 206.80 cm.
b. find the probability that the mean for 15 randomly selected distances is greater than 196.20 cm.
c. why can the normal distribution be used in part (b), even though the sample size does not exceed 30?

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
