This image contains a Hebrew text related to a scientific experiment involving sleep deprivation and its effects on sleep latency. Here's a summary and clarification of the problem:

The experiment tests how chronic sleep deprivation influences the time it takes for participants to fall asleep, known as sleep latency. In this experiment, subjects underwent different tests where their sleep was restricted to 8 hours and then deprived for 24 hours. The effect was measured in terms of sleep latency before and after the sleep deprivation.

The question asks you to determine whether the additional analysis would show that the average sleep latency after deprivation is:

- Greater than before (גדול מ-)
- Smaller than before (קטן מ-)
- Equal to before (שווה ל-)
- Cannot be determined (לא ניתן לדעת)

### The question seeks to compare the sleep latency after the 24-hour sleep deprivation with that of the initial sleep condition.

Do you need any specific mathematical help or additional details on how to solve this problem? Would you like more explanation on how to approach such analysis?

Here are 5 related questions:
1. What statistical test would be most appropriate to compare the two sleep latency periods?
2. How would sample size affect the validity of the sleep deprivation study?
3. Can sleep deprivation affect other aspects of health, beyond sleep latency?
4. What is the concept of "average sleep latency," and how is it measured in clinical trials?
5. How would we compute the average change in sleep latency for each participant?

### Tip:
When comparing means in an experiment, always ensure that the sample sizes are sufficient and that randomization minimizes biases that could affect the results.

How does sleep deprivation affect sleep latency? The experiment compares sleep latency before and after a 24-hour sleep deprivation period.

This page explains how to analyze the effect of sleep deprivation on sleep latency using statistical methods. The problem involves comparing average sleep latency before and after sleep deprivation using t-tests. Suitable for students in Grades 10-12.
