Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.

Normal Distribution

Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!

**Title: Statistical Analysis of Mosquito Populations in Regions**

**Introduction:**

A research study aims to determine if the proportion of mosquitoes carrying a particular disease is higher in Region 1 compared to Region 2. Data from mosquito samples gathered in each region are analyzed to draw conclusions about the regional differences in disease prevalence.

**Data Summary:**

- **Region 1 Sample:**
- Total mosquitoes trapped: 1,323
- Mosquitoes testing positive for the disease: 1,045

- **Region 2 Sample:**
- Total mosquitoes trapped: 1,559
- Mosquitoes testing positive for the disease: 839

**Research Objective:**
The objective is to test the hypothesis that the proportion of disease-carrying mosquitoes in Region 1 is greater than in Region 2.

**Statistical Approach:**
- **Test Statistic:** $ z = 1.62 $
- The task involves determining the corresponding $ p $-value using a standard normal distribution (z-table).

**Z-Table Analysis:**

An accompanying z-table is provided to find the $ p $-value for the test statistic. The table format displays z-scores at varying decimal levels, allowing precise determination of statistical significance:

```
z \ 0.00 0.01 0.02 ...
1.0 0.841 0.844 0.846
1.1 0.864 0.867 0.869
1.2 0.885 0.888 0.891
1.3 0.903 0.905 0.908
1.4 0.919 0.921 0.922
1.5 0.933 0.935 0.937
1.6 0.945 0.947 0.948
```

**Instructions for $ p $-Value Computation:**

Locate the z-score of 1.62 in the table, using the row for 1.6 and the column for 0.02 to find the corresponding $ p $-value. This value demonstrates the probability that the observed statistical result could occur

To check the effect of hot temperatures on the elasticity of two brands of rubber bands, one box of Brand A and one box of Brand B rubber bands are tested. Ten bands from the Brand A box are placed in a warm car in the sun for two hours and ten bands from the Brand B box are kept at room temperature. The amount of stretch before the breakage is measured on each rubber band, and the mean for the hot bands is compared to the mean for the others. Is this a good experimental design? No, because No, because temperature is confounded No, because No, because the means are more than two more not proper Yes brands should temperatures should be used. statistics for be used. with brand. comparison.
Polyunsaturated fatty acids in the diet favorably affect several risk factors for cardiovascular disease. The principal dietary polyunsaturated fat is linoleic acid. Suppose we randomly selected twelve adults for our study. We took their blood pressure measurements (systolic blood pressure) at the start and recorded them for each adult. Then we placed required these adults to consume 23g/day of safflower oil which is high in linoleic acid for four weeks. At the end of the four weeks, we took another systolic blood pressure(SBP) measurement. The paired data is provided below: Subject 1 2 3 4 5 6 7 8 9 10 11 12 Baseline SBP 119.67 100.00 123.56 109.89 96.22 133.33 115.78 126.39 122.78 117.44 111.33 92.39 1-month SBP 117.33 98.78 123.83 107.67 95.67 128.89 113.22 121.56 126.33 110.39 107.00 93.06 Use the appropriate nonparametric test at alpha level of 0.05, to test whether the diet heavy in linoleic acid increases systolic blood pressure (SBP).
How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. The table shows the result of the experiment. The researchers will use a chi-square test for homogeneity to analyze the findings. Hatching status Yes No Total Cold 16 11 27 Water Temperature Neutral Hot 38 75 18 56 104 Total 129 58 187 Which of the following is false? All of the conditions are met for conducting a chi- square test for homogeneity. The data came from 3 groups in a randomized experiment. All expected counts are at least 5. The 10% condition is met. The 10% condition is not needed because the eggs were not randomly selected from the population. Incorrect
