(A) 0.013 (B) 0.025 (C) 0.500 (D) 1.960 (E) None of the above. Working... In general, the sample size, n, should be above about 30 in order for the Central Limit Theorem to be applicable.

Loading... I can do it manually, but it's a lot of button mashing. But if the original population is badly skewed, has multiple peaks, and/or has outliers, researchers like the sample size to be even larger.

Hooray for The System! Skip navigation UploadSign inSearch Loading... The choice of t statistic versus z-score does not make much practical difference when the sample size is very large.

Next, we find the standard error of the mean, using the following equation: SEx = s / sqrt( n ) = 0.4 / sqrt( 900 ) = 0.4 / 30 = AmyRobinCole 5,869 views 11:28 How to find the confidence interval of the proportion in the TI-84 calculator - Duration: 3:21. In this situation, neither the t statistic nor the z-score should be used to compute critical values.

How To Find Margin Of Error On Ti 83 To express the critical value as a t statistic, follow these steps. How To Find Margin Of Error With Confidence Interval On Ti-84 The condition you need to meet in order to use a z*-value in the margin of error formula for a sample mean is either: 1) The original population has a normal

A t*-value is one that comes from a t-distribution with n - 1 degrees of freedom. That is, the critical value would still have been 1.96. When estimating a mean score or a proportion from a single sample, DF is equal to the sample size minus one. The critical t statistic (t*) is the t statistic having degrees of freedom equal to DF and a cumulative probability equal to the critical probability (p*). How To Find Sample Size On Ti 83

The central limit theorem states that the sampling distribution of a statistic will be nearly normal, if the sample size is large enough. Note: The larger the sample size, the more closely the t distribution looks like the normal distribution.

For example, the area between z*=1.28 and z=-1.28 is approximately 0.80. drenniemath 37,779 views 11:04 confidence intervals, margin of error, and sample size.wmv - Duration: 11:28. Solution The correct answer is (B). When the sampling distribution is nearly normal, the critical value can be expressed as a t score or as a z score.

To find the critical value, we take the following steps. Loading... This section describes how to find the critical value, when the sampling distribution of the statistic is normal or nearly normal. We could devise a sample design to ensure that our sample estimate will not differ from the true population value by more than, say, 5 percent (the margin of error) 90
