t Statistic of Normal Distribution Solution

STEP 0: Pre-Calculation Summary

Formula Used

t Statistic of Normal Distribution = (Sample Mean-Population Mean)/(Sample Standard Deviation/sqrt(Sample Size))
t_Normal = (x̄-μ)/(s/sqrt(N))
This formula uses 1 Functions, 5 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

t Statistic of Normal Distribution - t Statistic of Normal Distribution is the t statistic calculated from a normal distribution.
Sample Mean - Sample Mean is the average value of all the data points in a specific sample.
Population Mean - Population Mean is the average value of all the values in a population.
Sample Standard Deviation - Sample Standard Deviation is the measure of how much the values in a specific sample vary.
Sample Size - Sample Size is the total number of individuals or items included in a specific sample.

STEP 1: Convert Input(s) to Base Unit

Sample Mean: 48 --> No Conversion Required
Population Mean: 28 --> No Conversion Required
Sample Standard Deviation: 15 --> No Conversion Required
Sample Size: 10 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_Normal = (x̄-μ)/(s/sqrt(N)) --> (48-28)/(15/sqrt(10))

Evaluating ... ...

t_Normal = 4.21637021355784

STEP 3: Convert Result to Output's Unit

4.21637021355784 --> No Conversion Required

FINAL ANSWER

4.21637021355784 ≈ 4.21637 <-- t Statistic of Normal Distribution

What is the t test in Statistics?

A t test is a statistical test that is used to compare the means of two groups. It is often used in hypothesis testing to determine whether a process or treatment actually has an effect on the population of interest, or whether two groups are different from one another. There are three t tests to compare means: a one-sample t test, a two-sample t test and a paired t test.

How to Calculate t Statistic of Normal Distribution?

t Statistic of Normal Distribution calculator uses t Statistic of Normal Distribution = (Sample Mean-Population Mean)/(Sample Standard Deviation/sqrt(Sample Size)) to calculate the t Statistic of Normal Distribution, t Statistic of Normal Distribution formula is defined as the the t statistic calculated from a normal distribution. t Statistic of Normal Distribution is denoted by t_Normal symbol.

How to calculate t Statistic of Normal Distribution using this online calculator? To use this online calculator for t Statistic of Normal Distribution, enter Sample Mean (x̄), Population Mean (μ), Sample Standard Deviation (s) & Sample Size (N) and hit the calculate button. Here is how the t Statistic of Normal Distribution calculation can be explained with given input values -> 4.21637 = (48-28)/(15/sqrt(10)).
