"Trydint" bubble-gum company claims that 3 out of 10 people prefer their gum to "Eklypse". Test their claim at the 90 confidence level.The null and alternative hypothesis in symbols would be H0:p=0.3H1:p≠0.3 The null hypothesis in words would be: The proportion of all people that prefer Trydint gum is 0. Based on a sample of 100 people, 25 said they prefer "Trydint" gum to "Eklypse".The point estimate is: 0.250The 90 % confidence interval is: to (to 3 decimals)Based on this we: Reject the null hypothesis Fail to reject the null hypothesis
A 90% confidence interval for p is given as (0.26,0.54). How large was the sample used to construct this interval? (Round up to the nearest observation.)
In a random sample of 392 people that were tested for the Norcovirus, it was found that 314 did not have the virus. A 97% confidence interval was constructed to estimate the proportion of the population that does not have the Norcovirus. This confidence interval came out to be (0.76,0.84).
We wish to estimate what percent of adult residents in a certain county are parents. Out of 200 adult residents sampled, 150 had kids. Based on this, construct a 99% confidence interval for the proportion ππ of adult residents who are parents in this county.
Alessandro constructed three confidence intervals, all from the same random sample. The confidence levels are 90%, 95%, and 99%. The confidence intervals are Ⅰ. <6.2<μ7.8 Ⅱ. <6.1<μ7.9 Ⅲ. <5.8<μ8.2 Unfortunately, Alessandro has forgotten which confidence interval has which level. Match each confidence interval with its level.
Sal knows that parties of people on average spend 75 minutes at their restaurant. They wonder if this average is significantly different on the weekends. They found the average time spent by the 30 parties which dined there this weekend was 82 minutes with a SD of 17 minutes. Assume an alpha of .05. The lower end of the 95% confidence interval is and the higher end of the 95% confidence interval is.
Both, the Cohen's d and confidence interval, measure the impact of the IV on the DV. The only difference is that the confidence interval does so for the population, whereas the Cohen's d does so for the sample.
A researcher surveys a group of college students to determine the negative life events that they experienced in the past 5 years and their current feeling of well-being. For N = 18 participants with 2 or fewer negative experiences, the average well-being score was X = 42 with SS = 398. For the N = 16 participants with 5 to 10 negative experiences the average score is X = 48.6 with SS = 370. Construct a 95% confidence interval for the difference between the population means for the two groups.
We wish to estimate what percent of adult residents in a certain county are parents. Out of 100 adult residents sampled, 48 had kids. Based on this, construct a 90% confidence interval for the proportion ππ of adult residents who are parents in this county.
A researcher wants to estimate the true proportion of Americans who suffer side-effects after taking a particular medication. A 99% confidence interval for the true proportion of Americans who suffer side-effects after taking the particular medication was found to be (0.024, 0.160). If a hypothesis test is conducted with the hypotheses, H,: p = 0.10 vs H: p# 0.10 , what would be the most likely conclusion? Select one: a. There is very strong evidence that p 0.10. Ob. There is little to no evidence that p = 0.10. c. There is little to no evidence that p # 0.10. d. Cannot tell.
Express the confidence interval (33.6 % , 42.4 % ) in the form of p ± E.
Under what circumstances is a t statistic used instead of a z-score for a hypothesis test? Justin wants to know whether a commonly prescribed drug does improve the attention span of students with attention deficit disorder (ADD). He knows that the mean attention span for students with ADD who are not taking the drug is 2.3 minutes long. His sample of 12 students taking the drug yielded a mean of 4.6 minutes. Justin can find no information regarding σx , so he calculated s2x =1.96. Determine the critical region using a one-tailed test with alpha = .05. Conduct the hypothesis test (Do the math and compare the t-critical and t-obtained values). State your conclusions in terms of H0 (Should you reject the H0 or fail to reject/accept the H0). Based on your analysis, is there a relationship between the drug and attention span?
