Question

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.
