Solved examples of T-Distribution Example:The CEO of light bulbs manufacturing company claims that an average light bulb lasts 300 days. A researcher randomly selects 15 bulbs for testing. The sampled bulbs last an average of 290 days, with a standard deviation of 50 days. If the CEO’s cl...

T distribution is used to make assumptions for a mean when the population standard deviation is not known to us and the sample size is small. Learn completely here at BYJU’S.
Once the critical t score is determined, you will need to find the t score for your information to determine whether or not to reject your hypothesis. The formula for the t score is the sample mean minus the population mean, all over the sample standard deviation divided by the squ...

A Poisson distribution describes the probability of an event happening a certain number of times (k) within a given interval of time or space.
In this case, t-scores are used. To estimate a population mean, statisticians use a confidence interval for mean formula. CI for Mean Using z-Distribution There is a separate confidence interval formula when using the z-distribution to estimate population parameters. This is the formula to use...

European options can be priced when returns follow a Student's t-distribution, provided that the asset is capped in value or the distribution is truncated. We call pricing of options using a log Student's t-distribution a Gosset approach, in honour of W.
