Answer #1

"DATA" in TI calculator allows entry in columns as data given for conducting the statistical testing of hypothesis.

The "STATS" button has three options-- 'EDIT','CALC' & 'TESTS'. While EDIT allows entry and modifications of DATA , CALC allows calculations using data and TESTS allows hypothesis testing like--

1. Z-Test(Test of hypothesis of mean for one large sample using raw data or summary data.),

2. T-Test(Test of hypothesis of mean for one small sample using raw data or summary data.),

3. 2 sample T Test(Test of hypothesis of means for two small samples using raw data or summary data.),

4. 2 sample Z Test(Test of hypothesis of means for two large samples using raw data or summary data.),

5. Z Interval(Calculates the specified Confidence Interval of the mean for one large sample using raw data or summary data.) ,

6. T Interval(Calculates the specified Confidence Interval of the mean for one small sample using raw data or summary data.),

7. 1-Prop ZTest(Test of hypothesis of proportions for one large sample using summary data.),

8. 2- Prop ZTest(Test of hypothesis of proportions for two large samples using summary data.) and others.
