**Testing Claims About Population Proportion Using Normal Approximation Method**---**Question:**Which of the following is NOT a requirement of testing a claim about a population proportion using the normal approximation method?**Choose the correct answer below:**- **A.** The sample observations are a simple random sample.- **B.** The conditions for a binomial distribution are satisfied.- **C.** The lowercase symbol, p, represents the probability of getting a test statistic at least as extreme as the one representing sample data and is needed to test the claim.- **D.** The conditions \( np \geq 5 \) and \( nq \geq 5 \) are both satisfied.---**Explanation:**This question aims to test your understanding of the requirements for using the normal approximation method when testing a claim about a population proportion. Carefully consider each option and choose the one that is NOT a requirement for this test.

Here, we have to choose the correct option regarding assumptions of testing the population…

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance & using the given sample statistics. Claim: p < 0.13; x = 0.05; Sample statistics: p=0.12, n = 25 Can the normal sampling distribution be used? A. No, because nq is less than 5. O B. No, because np is less than 5. OC. Yes, because both np and nq are greater than or equal to 5. D. Yes, because pq is greater than α = 0.05.
8. For a normal distribution with u = 500 and o = 100, find the following values: a. What X value separates the highest 10% of the distribution from the rest of the scores? b. What X values form the boundaries for the middle 60% of the distribution? %3D c. What is the probability of randomly selecting a score greater than X = 475?
a) State the mean and standard deviation of the standard normal curve. b) Find the z-score for which 95% of the distribution’s area lies between –z and z. c) Extending the meaning in part b, only 2.5% of z-scores would lie above ________.
Q6. If the test statistic for a left-tailed test is z = –1.72, then P-value is 0.9518.a. Trueb. False
Consider a hypothesis test of difference of means for two independent populations x1 and x2. Suppose that both sample sizes are greater than 30 and that you know ?1 but not ?2. Is it standard practice to use the normal distribution or a Student's t distribution? Use the Student's t distribution because both sample sizes are greater than 30. Use the normal distribution because we do not know ?2. Use the normal distribution because both sample sizes are greater than 30. Use the Student's t distribution because we do not know ?2.
Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance α using the given sample statistics. Claim: p≠0.21; α=0.05; Sample statistics: p=0.16, n=175 Can the normal sampling distribution be used? A. Yes, because both np and nq are greater than or equal to 5. Your answer is correct. B. No, because np is less than 5. C. Yes, because pq is greater than α=0.05. D. No, because nq is less than 5. State the null and alternative hypotheses. A. H0: p≥0.21 Ha: p<0.21 B. H0: p=0.21 Ha: p≠0.21 This is the correct answer. C. H0: p≤0.21 Ha: p>0.21 Your answer is not correct. D. The test cannot be performed. Determine the critical value(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The critical value(s) is/are…
what assumptions are required for a z-score hypthesis test? A. all of the above B. The score in the sample are independant observations C. the scores are obtained by random sampling D. the distribution of sample means is normal
a) Determine the standard deviation (s) of sunflower heights in the test plot which wasnot fertilized and the Pseudo-Standard deviation (PSD) of sunflower heights in the test plotwhich was fertilized. b) Consider the following three statements A.If the median of X is greater than the mean of X than the distribution of X ispositively skewed. B.For Normal populations the median and the mean are approximately equal. C.The median and the Inter-quartile range are measures of variability in apopulation. c) Consider the following three statements A.The correlation between two positive quantities is always positive. B.If the correlation between X and Y is negative than the slope of the regressionline for predicting Y from X is negative. C.Pearsons correlation coefficient is always between -1 and +1. This is notnecessarily true for Spearmans correlation coefficient
