PROBLEM 1 It is well known that adult male heights follow a normal (Gaussian) distribution. The same is true of adult female heights. For general Canadian population in the range from 18 to 79 years of age, male height follows N(175 cm;7.5 cm), while female height follows N(162 cm; 7.5 cm). Depending on your gender, determine the following: I am (select one): O FEMALE MALE A. Make a (rough) sketch of the distribution, label it indicating the mean and your...

Life expectancy in a country is known to follow a left-skewed distribution with a mean value of 78.26 years and a standard deviation of 4.29 years. Suppose we take a random sample of 8 members of this country, and calculate their average life expectancy. What is the probably that this sample has an average value of at most 78.52 years? Select one: a. 0.6844 b. 0.9127 c. 0.4800 d. 0.3156 e. We cannot answer this question with the information given.

1) Rate data often follow a lognormal distribution. Average power usage (dB per hour) for a particular company is studied and is known to have a lognormal distribution with parameters μ = 4 and σ = 2. What is the probability that the company uses more than 270 dB during any particular hour? 2) A certain type of device has an advertised failure rate of 0.01 per hour. The failure rate is constant and the exponential distribution applies. (a) What...
