**Question:**Suppose we are counting successes in a Poisson process where we expect 12 successes per hour. What is the variance in the number of successes during a 25 minute period?**Options:**- 3- 5- 6- 25**Explanation:**In a Poisson process, the variance is equal to the mean. To find the mean for a 25-minute period, we convert 25 minutes to hours: 25 minutes = 25/60 hours ≈ 0.4167 hours.The expected number of successes in 0.4167 hours is:Mean = 12 successes/hour * 0.4167 hours ≈ 5.Therefore, the variance is also 5. The correct answer is 5.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

4. Researchers working for a sports drink company would like to know if a new blend if its popular sports drink can help improve marathon runners' final running time. Marathon times, Y, are known to follow a Normal distribution. Suppose that runners using the old blend sports drink have a mean finishing time of 300 minutes (µ = 300 minutes). A random sample of 20 runners was selected to use the new blend of sports drink in a marathon, finishing with an average time of 270 minutes and a standard deviation of 20 minutes (y = 270 min, s = 20 min). Can it be claimed that the new blend lowers finishing times? COr is it possible that random chance alone can explain the discrepancy?

Old Faithful is a geyser located in Yellowstone National Park in Wyoming, USA. Millions of travelers come from afar to witness Old Faithful's eruptions each year. Travelers to Yellowstone are told that Old Faithful is expected to erupt, on average, every 7272 minutes, but park scientists suspect that this average is incorrect. To investigate, the scientists determine the waiting time until the next eruption for a random sample of 272272 Old Faithful eruptions. The waiting times have a mean of 70.897 minutes and a standard deviation of 13.595 minutes. You will use these data to carry out a significance test at the ?α = 0.05 level.
