The average salary for graduates entering the actuarial field is $63000. If the salaries are normally distributed with a standard deviation of $5000, what is the probability that an individual graduate will have a salary over $67000?
At a large publishing company, the mean age of proofreaders is 36.2 years and the standard deviation is 3.7 years. Assume the variable is normally distributed. Round intermediate z -value calculations to two decimal places and the final answers to at least four decimal places. If a random sample of 25 proofreaders is selected, find the probability that the mean age of the proofreaders in the sample will be between 36.5 and 38 years. Assume that the sample is taken from a large population and the correction factor can be ignored.
Assume that females have pulse rates that are normally distributed with a mean of u=74.0 beats per minute and a standard deviation of o = 12.5 beats per minute. if 4 adult females are randomly, find the probability that they have pulse rates with a mean between 67 beats per minute and 81 beats per minute.
The compressive strength of concrete is normally distributed with mean 2500 psi and standard 50 psi. Find the probability that a random sample of n=5 specimens will have a sample mean diameter that falls in the interval from 2499 psi to 2510 psi. Answers in 4 significant figures.
The capacitance of capacitors produced by a machine is approximately normally distributed with a mean of µ = 1000 µF and a standard deviation of 80 µF. A sample of 16 capacitors is taken and the average of the capacitances values is computed. Based from the manufacturer’s standards, the machine is working properly if the computed average capacitance falls within 950 µF and 1050 µF. Otherwise, we conclude that µ ≠ 1000 µF. a.) Determine the probability of committing a type I error when µ = 1000 µF.b.) Determine the probability of committing a type II error when µ = 1080 µF. Hint: Use the sampling distribution of the mean when computing the probabilities
A batch of 3000 inverters from the production line has a mean output voltage of 337.8 V and the Standard deviation of the output voltage is 3.D V (where D is the last two digits of your student number inserted to the right of the decimal point). If the voltages of the produced inverters are assumed to be normally distributed, determine the following: The number of inverters with output voltages greater than 336.9 V. The number of inverters with output voltages less than 337.1 V, The number of inverters with output voltages between 336.2 V and 339.8 V.
Today, the waves are crashing onto the beach every 5.8 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 5.8 seconds. Round to 4 decimal places where possible. The probability that it will take longer than 1.96 seconds for the wave to crash onto the beach after the person arrives is P(x ≥≥ 1.96) = Find the minimum for the upper quartile. seconds
The depth to which a pile can be driven without hitting the rock stratum is denoted as H (see figure below). For a certain construction site, suppose that this depth has a log-normal distribution with mean of 30 ft and coefficient of variation of 20%. In order to provide satisfactory support, a pile should be embedded 1 ft into the rock stratum. What is the probability that a pile of length 40 ft will not anchor satisfactorily into the rock?

A batch of 3000 inverters from the production line have a mean output voltage of 337.8 V and the Standard deviation of the output voltage is 3.D V (where D is the last two digits of your student number inserted to the right of the decimal point). If the voltages of the produced inverters are assumed to be normally distributed, determine the following: The number of inverters with output voltages greater than 336.9 V. The number of inverters with output voltages less than 337.1 V, The number of inverters with output voltages between 336.2 V and 339.8 V. For this problem you should use the table of z-values shown in Figure below.
According to a medical study, it takes about 47.5 hrs, on average, for Roseola virus to fade away in infected patients (children). Assuming that the fading times of Roseola virus in infected patients are normally distributed with standard deviation 0.35, what's the probability of having a random case where the fading time of the virus in an infected patient is less than 47.85 hours? Find the answer without using the normalcdf(...) function.
