Two geysers that are near to each other are labelled as Geyser
A and Geyser B. The time between eruptions for a given geyser
follows an exponential distribution. The eruption times of the
two geysers are independent of one another. The mean
amount of time between eruptions of Geyser A is 39 minutes,
and the mean amount of time between eruptions of Geyser B
is 66 minutes. Given that exactly one of the geysers erupts
within the next 49 minutes, determine the probability that it
will be Geyser A.

2. Losses have an exponential distribution with a mean of 2,000. An insurance company will pay
the amount of each claim in excess of a deductible of 400. Determine the variance of the
amount paid by the insurance company for one claim, including the possibility that the amount
paid is zero.
(a) The following data represent the number of salespeople for a
certain company for 6 consecutive years:
Year
1 2 3 4 5 6
No. of Salespeople 13 18 22 29 41 50
Human Resource Manager (HRM) was advised by the company to
make projection for the next consecutive year based on the
company's carrying capacity of 70 salespeople. However, the HRM
used an exponential model. Determine the percentage error he
made in his projection.(NB: Correct all computations to 4
decimal places).

- Can you help me on problem 2 A-Carrow_forward6. A small company can employ 3 workers. Each worker independently stays on the job for an exponentially distributed time with a mean of one year and then quits. When a worker quits, it takes the company an exponentially distributed time with a mean of 1/10 of a year to hire a replacement for that worker (independently of how long it takes to replace other workers). If the company takes in $1000 per day in revenue when it has 3 workers, $800 per day when it has 2 workers, and $500 per day when it has 0 or 1 workers, what is the company's long-run average daily revenue?arrow_forwardFundamentals of Biostatistics 8th ED chapter7 Problemes 14-15-16arrow_forward
- Age is a variable that is important in most if not all epidemiological studies of health because our health is so strongly related to age. The following table is a two-dimensional table that summarizes the distribution of age in a certain population every five years starting with 1970 (the first row) to 2000 (the last row). Each row contains information for one year. Reading across the row (over the column), the table shows the number of individuals in each age group. If you choose this option, please do the following: (a) using the data provided, produce a new two-dimensional table that shows, for each year, the percentage of that year’s total population in each age interval (Tip! In each row, the sum of your percentages should be 100%); and (b) write a brief report (a paragraph or so, no more!) on what these summaries suggest regarding the possibility (or lack thereof) of changes over time in the age distribution of this population.

STATISTICS. An analyst in the real estate business is interested in the relationship between the cost of the monthly rent of an apartment and the size of an apartment, in big cities. She gathers data for apartment buildings in 12 cities in 12 different states. In each city, she gets the numbers for at least 5 different buildings and at least 40 apartments in each building. She reaches the following conclusion: the rental cost of a 2-bedroom apartment is 50% more than the rental cost of a 1-bedroom apartment, and the rental cost of a 3-bedroom apartment is 50% more than the rental cost of a 2-bedroom apartment. Based on the paragraph, what is the minimum number of apartments she collected data on? Do you think her sample was large enough to be statistically valid?

Hint: Under the latter hypothesis, model the number of accidents each month as a Multi- nomial random variable with the appropriate probabilities and conduct a goodness-of-fit test.
