How do you solve this problem. You drive to work. Drive time mean 30 min standard deviation 4 min. Workday begins at 9am. What time should you leave so that probability on time is 95 percent?

if standard deviation is 4 minutes 95% probability is about 2 standard deviations (actually 1.96) so you would need to allow 30 + 8 = 38 minutes

What is the probability that a machine take an average of 10 minutes to complete a task with a standard deviation of 1.5 minuetes What is the probability that task will take 8 and 11 minutes?

Time is a continuous variable and so the probability that an event takes any particular value is always 0.

The probability of a phone being answered at 2 min given the average time is 3?

The probability of a phone being answered in 2 minutes, given that the average time is 3 minutes, is not specified in the information given. More details or specific probabilities are needed to determine the answer.

What is the proportion of students who wake up before 11am if a survey shows that the average wake up time is 9.45 with a standard deviation of 65 minutes and it is an approximate normal distribution?

You need to ask 1 question at a time, rewording it into 200 characters or less - it helps you to actually think about what is required instead of getting others to do your work for you. The probability is the area under the normal curve between -&infin; and the z-value corresponding to 11:00 for a mean of 9:45 and a standard deviation of 65 minutes. When using single tailed tables, they give the area between the mean and the z-value, ranging from 0 to 0.5. So to find the area between -&infin; and the z-value it is the value form the single-tailed table of the z value plus 0.5 For working with time, it will be easier to work in minutes. 9:45 to 11:00 is 1 hr 15 minutes = 75 minutes = x - &micro; z = (x - &micro;)/standard deviation = 75/65 &asymp; 1.154 &rarr; area using single-tailed tables is approx 0.3758 &rarr; probability &asymp; 0.5 + 0.3757 = 0.8757 or approx 87.6%

What percentage of calls are completed between 100 and 120 minutes with a mean time of 100 minutes for office calls with a standard deviation of 25 minutes?

Mean = 100 Standard Deviation = 25 (120 -100) / 25 = 0.80 th z value of .80 from the table = .2881 P(100-120) = 28.81% What percentage of calls are completed in less than 60 minutes ? (60 - 100) / 25 = - 1.6 from the table the z value is .4452 (one side), then : .5000 - .4452 = .0548 P(60) = 5.48%

Fix-It Copiers advertises a mean time of 100 minutes for office calls with a standard deviation of 25 minutes What percentage of calls are completed?

There is no information on how much time can be spent on a call.

If 1000 students take a test that has a mean of 40 minutes a standard deviation of 8 minutes and is normally distributed how many would you expect would finish in less than 40 minutes?

The expected number is 500.

What is the probability of a class running between 51.25 and 51.5 minutes if the uniform distribution is between 50 and 52?

The probability is (51.5-51.25)/(52-50) = 0.25/2 = 0.125

Calculate percent standard deviation of 1.5 percent?

It has been determined that the wait-time for computer support is normally distributed with a mean of 30 minutes and a standard deviation of 5 min. If 100 people call, how many would you expect to wait more than 30 min? (use logic here)

Standard running time for 10klms?

Between 1 hour and 1 hour, 20 minutes.

1/14

What is the qualifying time for the fastest 5 percent of all runners if the average finishing time is 5 minutes 17 seconds with standard deviation of 12 seconds?

Assuming a normal distribution: For the fastest 5% we need to find the z value which gives 100% - 5% = 95% of the area under the normal curve (from -&infin;). Using single tailed tables, we need the z value which gives 95% - 50% = 0.45 (above the mean); this is found to be z &asymp; 1.645 z = (value - mean)/standard deviation &rarr; value = mean + z &times; standard deviation &asymp; 5 min 17 sec + 1.645 &times; 12 sec &asymp; 5 min 17 sec + 20 s = 5 min 37 sec
