According to a human resources report, a worker in the industrial countries spends on average 419 minutes a day on the job. suppose the standard deviation of time spent on the job is 26 minutes. a. if the distribution of time spent on the job is approximately bell shaped, between what two times would 68% of the figures be? enter the lower limit for the interval where 68% of the values would fall to enter the upper limit for the interval where 68% of the values would fall b. if the distribution of time spent on the job is approximately bell shaped, between what two times would 95% of the figures be? enter the lower limit for the interval where 95% of the values would fall to enter the upper limit for the interval where 95% of the values would fall c. if the distribution of time spent on the job is approximately bell shaped, between what two times would 99.7% of the figures be? enter the lower limit for the interval where 99.7% of the values would fall to enter the upper limit for the interval where 99.7% of the values would fall d. if the shape of the distribution of times is unknown, approximately what percentage of the times would be between 358 and 480 minutes? enter percentages rounded to 1 decimal place % (round the intermediate values to 3 decimal places. round your answer to 1 decimal place.)
