Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Question

What is the null and alt. hypothesis? How would the results be interpreted?

**Topic 7: Object Recognition in Right-Handed Individuals**

A neuropsychologist hypothesized that right-handed people would recognize objects placed in their right hands more quickly than those placed in their left hands when blindfolded. The table below represents the number of objects each participant could identify in 2 minutes using each hand.

| Participant No. | Left Hand | Right Hand |
|-----------------|-----------|------------|
| 1 | 8 | 10 |
| 2 | 5 | 9 |
| 3 | 11 | 14 |
| 4 | 9 | 7 |
| 5 | 7 | 10 |
| 6 | 8 | 5 |
| 7 | 10 | 15 |
| 8 | 7 | 7 |
| 9 | 12 | 11 |
| 10 | 6 | 12 |
| 11 | 11 | 11 |
| 12 | 9 | 10 |

**Graph/Diagram Explanation:**

This data is presented in a table format with three columns. The first column lists participant numbers, the second shows the number of objects identified with the left hand, and the third shows the number identified with the right hand.

**Statistical Analysis Task:**

a. Use Formula 11.1 to test the null hypothesis of no difference between the two hands' object recognition abilities (α = 0.05, two-tailed test).
