One Sample t Statistic for Mean Solution

STEP 0: Pre-Calculation Summary

Formula Used

t Statistic = (Sample Mean-Population Mean)/Standard Error
t = (x̄-μ_Population)/SE
This formula uses 4 Variables

Variables Used

t Statistic - t Statistic is the value obtained from a t-test, which compares the means of two groups to determine if they are significantly different.
Sample Mean - Sample Mean is the average of a set of values from a sample. It provides an estimate of the population mean and is a statistic because it describes the sample and is calculated from sample data.
Population Mean - Population Mean is the average of all the values in a population. It represents the central tendency of the entire group and is a parameter because it describes the entire population.
Standard Error - Standard Error is the measure of the variability of sample statistics, particularly the sample mean. It quantifies the precision of the sample mean as an estimate of the population mean.

STEP 1: Convert Input(s) to Base Unit

Sample Mean: 25 --> No Conversion Required
Population Mean: 20 --> No Conversion Required
Standard Error: 2.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t = (x̄-μ_Population)/SE --> (25-20)/2.5

Evaluating ... ...

t = 2

STEP 3: Convert Result to Output's Unit

2 --> No Conversion Required

FINAL ANSWER

2 <-- t Statistic

What is Hypothesis Testing in Statistics?

Hypothesis Testing is a statistical method used to determine whether there is evidence in a sample of data to suggest that a certain condition or relationship exists in a larger population. The process involves specifying a null hypothesis, which represents the default assumption or status quo, and an alternative hypothesis, which represents the claim or condition that is being tested.
Then a test statistic is calculated based on the sample data, and a p-value is determined, which represents the probability of obtaining the observed test statistic (or a more extreme value) under the assumption that the null hypothesis is true. If the p-value is less than a pre-determined significance level (usually 0.05), the null hypothesis is rejected in favor of the alternative hypothesis, indicating that there is significant evidence to suggest that the condition or relationship exists in the larger population.
