4. Describe in words the population, estimated parameter, and random variable in the context of the problem. If the population which is sampled from differs from the population of interest, explain briefly what the difference is. (a) A researcher investigating the health of North Atlantic right whales randomly samples 10 radio-tagged NA right whales, locates each one during a three-day period around August 23, 2025 and measures the length of each whale in metres. The sample mean of the lengths of the whale is calculated.

We decide to invite 200 women, through our friends’ friends, in romantic dating relationships to an extra credit survey opportunity and present them with the same “possible infidelity scenario.” After listening, the participant is then asked “Considering your current relationship partner and how you normally deal with things, how would you respond to this?” After data collection, we organize all the women’s responses into either “Direct” or “Indirect” confrontation strategies: We end up with 168 women would use direct strategies and 32 that would use indirect strategies. What type of sampling was done for this study?

INSTRUCTION You are supposed to create a folder on the desktop with your index number and computer number (where applicable) example: 01100054 D 001 . Use SPSS for the data analysis and copy only relevant output to Microsoft office for your write ups. Save your write-ups with your index number. QUESTION 4 [20 MARKS] Are a person's brain size and body size predictive of his or her intelligence? In answering the above research question, some researchers (Willerman, et al, 1991) collected the following data ("Intelligence") on a sample of $ n=38 $ college students as saved on your desktop computer. Response (y): Performance IQ scores (PIQ) from the revised Wechsler Adult Intelligence Scale. This variable served as the investigator's measure of the individual's intelligence. Potential predictor $ \left(x_{1}\right) $ : Brain size based on the count obtained from MRI scans (given Weight in pounds. Using the information and the data provided answer the following questions: i. Run descriptive statistics analysis on the variables in the dataset and comment on the mean and standard deviation of cach variable $ 2 \mathrm{mks} $ ii. Examine the normality (using descriptive techniques) of each variable in the dataset and comment on the result. $ 2 m k s $ iii. Perform correlation analysis among the study variables and comment on the association between PIQ and Brain Size and Height. $ 3 \mathrm{mks} $ iv. What statistical technique would lead you to examine the variation in the intelligence score? Imk v. State any two-assumptions underlying the procedure as stated in (iv) $ 2 \mathrm{mks} $

Use the limit comparison test to determine whether $\sum_{n=16}^{\infty} a_n = \sum_{n=16}^{\infty} \frac{5n^3 - 3n^2 + 16}{2 + 3n^4}$ converges or diverges. (a) Choose a series $\sum_{n=16}^{\infty} b_n$ with terms of the form $b_n = \frac{1}{n^p}$ and apply the limit comparison test. Write your answer as a fully simplified fraction. For $n \ge 16$, $\lim_{n \to \infty} \frac{a_n}{b_n} = \lim_{n \to \infty} \frac{\text{ }}{ ext{ }}$ (b) Evaluate the limit in the previous part. Enter $\infty$ as infinity and $-\infty$ as -infinity. If the limit does not exist, enter DNE. $\lim_{n \to \infty} \frac{a_n}{b_n} = \text{ }$ (c) By the limit comparison test, does the series converge, diverge, or is the test inconclusive? Choose
