In a test of hypothesis, the null hypothesis is that o = 2 and the alternative hypothesis is o> 2. The following samples were selected from two normal populations: X1 (22, 25, 32, 30, 27, 28, 24, 19, 20, 32, 28, 22, 30, 26, 22, 27, 23, 27, 32); x2 = (43, 34, 41, 35, 31, 27, 35, 33, 40, 35, 34, 40, 34, 35, 38, 40). What is the approximate p-value for this test? O c. 0.4385 a. 0.2808 O d. 0.1780 O e. 0.5339 O b. 0.5615

Grand Sun Buffet is a large restaurant chain. After paying for a meal at Grand Sun Buffet, customers are asked to rate the quality of the food as a 1, 2, 3, 4, or 5, where a rating of 1 means "not good" and 5 means "excellent". The customers' ratings have a population mean of u = 4.90, with a standard deviation of o = 1.88. Suppose that we will take a random sample of n = 10 customers' ratings. Let x represent the sample mean of the 10 customers' ratings. Consider the sampling distribution of the sample mean x. Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed. (a) Find H- (the mean of the sampling distribution of the sample mean). (b) Find o- (the standard deviation of the sampling distribution of the sample mean).
Which of the following is a two-tailed test? O Ho: µ = 89, H1: u 84 O Ho: µ = 54, H1: u # 54
. The term sample usually refers to a sample that ___ - Consists of people with chemical dependency problems - Uses the same group of individuals with a before/after measurement - Requires a dependent variable for hypothesis testing - Is randomly selected from two dependent populations
Two random samples are selected from two independent populations. A summary of the samples sizes, sample means, and sample standard deviations is given below: n1=41,n2=48,x¯1=56.1,x¯2=71.2,s1=5s2=10.6n1=41,x¯1=56.1,s1=5n2=48,x¯2=71.2,s2=10.6 Find a 94.5% confidence interval for the difference μ1−μ2μ1−μ2 of the means, assuming equal population variances. Confidence Interval =
A manufacturer claims that 10% of women using the "pill" suffer from side effects. The Federal Drug Administration (FDA) believes that the manufacturer's claim is too low and decides to test the manufacturer's claim at a 5 %. A random sample of 900 women who use the manufacturer's pill shows that 103 suffer side effects. The p-value of this test is: O a. 0.1144 Ob. 0.0644 O C. 0.1000 Od. 0.0743 e. 0.0144

The coach of a very popular men’s basketball team claims that the average distance the fans travel to the campus to watch a game is 35 miles. The team members feel otherwise. A sample of 16 fans who travel to games was randomly selected and yielded a mean of M= 36 miles and s= 5 miles. Test the coach’s claim at the 5% (.05) level of significance. one-tailed or two-tailed test: State the hypotheses: df= tα or t value for the critical region = sM = t (test statistic)= Decision:
In a survey of 180 females who recently completed high school, 75% were enrolled in college. In a survey of 160 males who recently completed high school,70 % were enrolled in college. At a=.009, can you reject the claim that there is no difference in the proportion of college enrollees between the two groups? Assume the random samples are independent. Complete parts (a) through (e).
