Question 3 (1.5 points) Match the TI-84 PLUS calculator command that would be used to find the confidence interval in each case. If the confidence interval cannot be constructed, choose "Cannot be done Sample size 12 Sample mean 94 Population Standard Deviation 14 Population is normal Sample size 19 Sample mean = 0.26 Population Standard Deviation Population is not normal 0.08 Sample size 21 Sample mean 14.2 Population Standard Deviation 0.18 Population is not normal 1. TInterval 2. Cannot be done Sample size- 85 Sample mean1091 Sample Standard Deviation-0.18 Population is not normal 3. ZInterval Sample size 100 Sample mean 20 Sample Standard Deviation-4 Sample size 44 Sample mean-0.86 Population Standard Deviation 0.0021 Save

Explanation / Answer

1. Everything is right. Cofidence interval can be calculated.

2. Since population is not normal. Thus, it can't be calculated.

3. Similar to 2. It cannot be done.

4. Population is not normal, it cannot be done.

5. t interval can be calculated
