The is the probability distribution used in place of the no

The _________ is the probability distribution used in place of the normal distribution to calculate a confidence interval when the population standard deviation is unknown.

binomial distribution

exponential distribution

student\'s t-distribution

uniform distribution

Solution

The _________ is the probability distribution used in place of the normal distribution to calculate a confidence interval when the population standard deviation is unknown.

student\'s t-distribution

the answer is student\'s t distribution because we dont know the standard deviation of the population

when we know the standard deviation of the population we use Z distribution

but for this case is t student distribtuion
