Voltage and Insulating Fluid. Researchers examined the time in minutes before an insulating fluid lost its insulating property. The following data are the breakdown times for eight samples of the fluid, which had been randomly allocated to receive one of two voltages of electricity:
Times (min) at 26 kV: 5.79 1579.52 2323.70
Times (min) at 28 kV: 68.8 108.29 110.29 426.07 1067.60
(Please explain/list every step in details)
1. Form two new variables by taking the logarithms of the breakdown times: Y1 = log breakdown time at 26 kV and Y2 = log breakdown time at 28 kV.
2. By hand, compute a 95% confidence interval for the difference in mean log breakdown times. Take the antilogarithms of the endpoints and express the result in a sentence.

A group of researchers estimates the mean length of time (in
minutes) the average U.S. adult spends watching television using
digital recorders and other forms of time-shifted television each
day. To do so, the group takes a random sample of 40 U.S. adults
and obtains the times (in minutes) listed below. Assume the
population standard deviation to be 6.5 minutes. construct a 90%
and 99% confidence interval for the population mean.

A company studied the number of lost-time accidents occurring at
its Brownsville, Texas, plant. Historical records show that of the
employees suffered lost-time accidents last year. Management
believes that a special safety program will reduce such accidents
to during the current year. In addition, it estimates that of
employees who had lost-time accidents last year will experience a
lost-time accident during the current year.

A pizza shop claims its average home delivery time is 27
minutes. A sample of 30 deliveries had a sample average of 30.7
minutes. Assume the population standard deviation for the shop's
deliveries is 7.1 minutes. Complete parts a and b below. a. Is
there support for the shop's claim using the criteria that the
sample average of 30.7 minutes falls within the symmetrical
interval that includes 95% of the sample means if the true
population mean is 27 minutes?...

Delta airlines quotes a flight time of 2 hours, 5 minutes for
its flight from Cincinnati to Tampa. Assume that the probability of
a flight time within any one-minute interval is the same as the
flight time within any other one-minute interval contained within
the larger interval, 120 and 140 minutes.
*State the objective: What is the probability
that the flight will be no more than 5 minutes late?

follows an exponential law of theta parameter. We know that 60% of
devices operate without failure for at least 2 years.
a) What is the average lifespan of the devices?
b) What is the time t such that 50% of the devices
operate less than t years?

(Estimated time allowance: 40-50 minutes)
Easy-Chair Corp. is considering replacing its existing equipment
that is used to produce comfort recline chairs. This existing
equipment was purchase 2 years ago at a base price of $100,000.
Installation costs at the time for this old equipment were $5,000.
The existing equipment is considered a 5-year class for MACRS. The
existing equipment can be sold today for $40,000 and for $0 in 3
years. The new equipment has a purchase price of $200,000...
