The degrees of freedom for the t test for comparing two population means when the population variances are equal is:- Sample 1 A) 19. 19 B) 20 C) 21 D) 18.87 N₁-12 S1-3 Sample 2 N₂-10 S2-2
When two births are randomly selected, the sample space for genders is bb, bg. gb, and gg. Assume that those four outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from two births. Does the mean of the sample proportions equal the proportion of girls in two births? Does the result suggest that a sample proportion an unbiased estimator of a population proportion? For the entire population, assume the probability of having a boy is the probability of having a girl is , and this is not affected by how many boys or girls have previously been born. 2 Determine the probabilities of each sample proportion. Probability Sample proportion of girls Tune intanare or cimnlifiad frartinne
In a two sample (independent-sample) test, what must be true if t = 0? Group of answer choices A)The two population means must be equal. B)The two sample means must be equal. C)The two sample variances must be equal. D)The two population means must be not equal.
If the sample data produce a test statistic (z-score) that is in the critical region, then which of the following is the appropriate conclusion for the test? O reject H₁ O fail to reject H₁ O fail to reject Ho O reject Ho
In a large class of introductory Statistics students, the professor has each person toss a coin 22 times and calculate the proportion of his or her tosses that were heads. Complete parts a through d below. a) Confirm that you can use a Normal model here. The Independence Assumption ▼ is not is satisfied because the sample proportions ▼ are are not independent of each other since one sample proportion ▼ does not affect can affect another sample proportion. The Success/Failure Condition ▼ is not is satisfied because np=nothing and nq=nothing, which are both ▼ greater than or equal to less than 10. (Type integers or decimals. Do not round.) b) Use the 68–95–99.7 Rule to describe the sampling distribution model. About 68% of the students should have proportions between nothing and nothing, about 95% between nothing and nothing, and about 99.7% between nothing and nothing. (Type integers or decimals rounded to four decimal…
Calculating sample variance requires a slight modification in the formula as compared to calculate in population variance. Why? a) the population parameter is equal to the sample statistic b) the sample variability is too difficult to measure directly c) samples have systematically more variability than the populations from which they are drawn d) samples have systematically less variability than the populations from which they are drawn
