The
Acme candy company claims that 60% of the job breaker is it
produces way more than 0.4 ounces. Suppose that 800 job breakers
are selected at random from the production lines. Use the range
rule of thumb to determine whether it is statistically significant
for the sample of 800 to contain 494 job breakers that weigh more
than 0.4 ounces. Consider as significant any result that differs
from the mean by more than two standard deviations. Show all work
using range rule of thumb required to obtain your answer. Clearly
state all important values involved.
