The Chi-Square Test for One Variance is a statistical test used to compare the variance of a sample to a known population variance. It is used to test a hypothesis about the population variance and is based on the assumption that the sample is drawn...

 (also called Two Sample Z Test for Proportions) Two Proportions Z Test A two-proportions z-test is a statistical test used to compare the proportions of two independent samples. It is used to test a hypothesis about the difference between the propor...

 Paired t-Test A paired t-test is a statistical test used to compare the means of two related samples or matched pairs. It is used to test a hypothesis about the difference between the means of the two samples. It is based on the assumption that the...

 A two-sample t-test is a statistical test used to compare the means of two different samples to determine if there is a significant difference between them. It is based on the assumption that the samples are drawn from populations with normal distri...

 A one-proportion z-test is a statistical test used to compare the proportion of a sample to a known population proportion. It is used to test a hypothesis about the population proportion and is based on the assumption that the sample is drawn from a...

 A one-sample t-test is a statistical test used to compare the mean of a sample to a known population mean. It is used to test a hypothesis about the population mean and is based on the assumption that the sample is drawn from a normally distributed...

The p-value is the probability of obtaining a test statistic that is equal to or more extreme than the one observed, assuming that the null hypothesis is true. It is used in hypothesis testing to determine the significance of the observed results. Fo...

 A two-sample z-test is a statistical test used to compare the means of two different samples to determine if there is a significant difference between them. It is based on the assumption that both samples are drawn from normally distributed populati...

 A one-sample z-test is a statistical test used to compare the mean of a sample to a known population mean. It is used to test a hypothesis about the population mean and is based on the assumption that the sample is drawn from a normally distributed...

Hypothesis testing is a fundamental tool in statistical analysis that allows us to make decisions about a population based on sample data. It involves formulating a hypothesis about a population parameter, collecting data, and using statistical techn...
