### Statistics and Probability Practice Questions Welcome to our educational platform's practice section. Below are several multiple-choice questions designed to help you practice statistical and probability concepts. These questions are suitable for students preparing for exams or anyone looking to sharpen their understanding of these topics. --- **Q14. Hypothesis Testing** In testing \( H_0 : \mu = 2 \) vs \( H_1 : \mu > 2 \) using \( \alpha = 0.1 \), a random sample of size \( n = 6 \) from a normal population with \( \bar{x} = 2.6 \), \( s = 0.4336 \) is obtained. The observed test statistic \( t \) is: - A) 2.44 - B) 3.39 - C) 1.22 - D) 1.13 **Q15. Probability with Mutually Exclusive Events** If \( P(Q) = 0.45 \), \( P(R) = 0.3 \) are mutually exclusive, then \( P(Q \cap R) \) is: - A) 0.3 - B) 0.45 - C) 0.12 - D) None **Q16. Confidence Interval Estimation** Suppose a 99% confidence interval for the population mean (\( \mu \)) is given by (123.7, 153.5). Find the point estimate of \( \mu \): - A) 2.575 - B) 277.2 - C) 138.6 - D) 137.6 *Assume that the random variable \( X \) is normally distributed, with mean \( \mu = 50 \) and standard deviation \( \sigma = 16 \). Answer the following two questions:* **Q17. Probability Calculation** The probability \( P(X > 70) \): - A) 0.8944 - B) 0.8819 - C) 0.0156 - D) 0 **Q18. Mode of a Normal Distribution** The mode of a random variable \( X \) is: - A) 66 - B) 45 - C) 50 - D) 3,125 **Q19. Standard Normal Variable** Let \( Z \) be
