There is not sufficient evidence to reject the claim that mean bulb life is at least 743 hours. Find the Statistics and probability:: T-test calculator; T-Test calculator. The Student's t-test is used to determine if means of two data sets differ significantly.

Standardized test statistic calculator

The calculator uses the probabilities from the student t distribution. For all t-tests see the easyT Excel Calculator : : Sample data is available. Fore more information on 2-Sample t-tests View the Comparing Two Means: 2 Sample t-test tutorial The standardized test statistic calculator is an easy way for anyone to compare the results with a 'Normal' population. The T-Scores and Z-Scores are comparatively similar. However, the T-Distribution here is a bit shorter & fatter as compared to normal distribution. Z-test calculator, formulas & example work with steps to estimate z-statistic (Z0), critical value of normal distribution (Ze) & test of hypothesis (H0) for large sample mean, proportion & two means or proportions difference in statistical surveys & experiments.

The Student's t-test is used to determine if means of two data sets differ significantly.

To calculate the p-value, this calculator needs 4 pieces of data: the test statistic, the sample size, the hypothesis testing type (left tail, right tail, or two-tail), and the significance level (α). When you're working with data, the numbers of the data itself is not very meaningful, because it's not standardized.

z = 1.7391. It means, you z-score are 1.7391 standard deviations above the mean.

28 Jul 2015 If you don't have access to the raw data, all you need is the mean, standard deviation, and sample size. For example, we had 30 participants

(d) Decide whether to reject or fail to reject the null hypothesis. If you run into a problem which asks you to find the standardized test statistic but does not give you the standard deviation, it is probably a proportion problem and this one is just that. Solution: Ho: p = 0.50; Ha: p ≠ 0.50. Calculate standardized test statistic (z) without standard deviation.? An environmental agency claimed more than 33% of consumers have stopped buying a certain product because of environmental concerns. In a random sample of 1020 consumers, you find 35% have stopped buying the product. At α = 0.04, do you have enough evidence to support the claim?
