The t distribution (aka, Student t distribution) is the sampling distribution of the t statistic. The values of the t statistic are given by: t = [ x - μ ] / [ s / sqrt( n ) ] When the population standard deviation is unknown, the sample size is less than 30, and the random variable x is approximately normally distributed, it follows a

From the definition of the t distribution, we know that T= Z A/1 = Z A ~t(1) , which allows us to find P X 1 + X 2 X 3 ≤3 =P X 1 + X 2 /4 X 3 3 2 /1 ≤ 9 4 =P T≤ 9 4 =0.87 , where the random variable T~t(1) and we used the t table of values.

Then, look at the table, the total area should be .6808 – .0808= .6. D. Standardize first, and we can get –2 < x < 1. Then, look at the table, the total area should be around 81.5%. B. Since the median is smaller than the mean, we can conclude it’s a skewed right graph. B. Since it is a skewed distribution, the median is better than mean. B.

The hypothesis test will use the Student’s t distribution. with degrees of freedom df = n – 1. Example: A used car dealer says that the mean price of a 2005 SUV is at least $23,900. It is suspected that this claim is incorrect and find that a random sample of 14 similar Nimbus SUVs has a mean price of $23,000 and a sample standard deviation ...
