An experiment is performed to determine whether the average nicotine content of one kind of cigarette exceeds that of another kind by 0.20 milligram. If n1 = 50 cigarettes of the first kind had an average nicotine content of ī¡ = 2.61 milligrams with a standard deviation of s̟ = 0.12 milligram, whereas n2 = 40 cigarettes of the other kind had an average nicotine content of ãz = 2.38 milligrams with a standard deviation of s2 = 0.14 milligram, test the null hypothesis µ1 – µ2 = 0.20 against the alternative hypothesis µ1 – µ2 · 0.20 at the 0.05 level of significance. %3D %3D 1,2,3,4

The State Association of Retired Teachers has recently taken flak from some of its members regarding the poor choice of the association's name. The association's by-laws require that more than 60 percent of the association must approve a name change. Rather than convene a meeting, it is first desired to use a sample to determine if meeting is necessary. Suppose the association decided to conduct a test of hypothesis using the following null and alternative hypotheses: H 0: p = 0.6 H 1: p > 0.6 Define a Type I Error in the context of this problem. Group of answer choices: A. They conclude that exactly 60% of the association wants a name change when that is, in fact, true. B. They conclude that exactly 60% of the association wants a name change when, in fact, that is not true. C. They conclude that more than 60% of the association wants a name change when that is, in fact, true. D. They conclude that more than 60% of the association wants a name change when, in fact,…
In exploring possible sites for a convenience store in a large neighbourhood, the retail chain wants to know the proportion of ratepayers in favour of the proposal. If the estimate is required to be within 0.1 of the true proportion, would a random sample of size n = 100 from the council records be sufficient for a 95% confidence interval of this precision?
For a one-sample test for a population proportion and sample size , why is it necessary that andare both at least 10 ?(A) The sample size must be large enough to support an assumption that the distribution of the population isapproximately normal.(B) The sample size must be large enough to support an assumption that the distribution of the sample isapproximately normal.(C) The sample size must be large enough to support an assumption that the sampling distribution of the sampleproportion is approximately normal.(D) The sample size must be large enough to support an assumption that the observations are independent.(E) The sample size must be large enough to support an assumption that the sample proportion is an unbiasedestimator of the population proportion
Given that the P-value for the hypothesis test is 0.000 when rounded to three decimal places, what do you conclude? What do the results indicate about the rule that women and children should be the first to be saved?
Assuming that all the assumptions of statistical hypothesis testing are met, based on the z-score of 1.96 and the sample size of 200, the appropriate conclusion for this test would be? a) P-value is under .05, we would reject the null hypothesis b) P-value is over .05, we would failed to reject the null hypothesis c) P-value is under .05, we would fail to reject the null hypothesis d) P-value is over .05, we would reject the null hypothesis
The largest group of moviegoers by age is the 40- to 59-year-old age group. This group constitutes 32% of the movie-going population. A theater complex randomly surveyed the customers over a three-week period and found that out of 423 surveyed, 170 were 40 to 59 years of age. At the 0.01 level of significance does this differ from the stated proportion? Which of the following hypothesis testing procedure fits the given problem?
If we have a sample of size 100 with sample mean breaking strength of 975 pounds from a population of rope with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength is less than 1000 pounds, what is the P-Value of our data?
Given the information for experiment 1, what is the null hypothesis, standard error, z-critical, and z-observed?
If we have a sample of size 100 with sample mean breaking strength of 1050 pounds from a population of rope with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength differs from 1000 pounds, what is the significance of our data? 2P(Z>1.25) 2P(Z<2.5) NONE OF THE OTHERS 2P(Z>2.5) P(Z<2.5)
Back in April and May of 1985, the Gallup organization conducted a poll to estimate the percentage of Americans who approved of how President Reagan was handling his job. At the 5% significance level, do the data suggest that the percentage of those who approved of Reagan increased from April to May in 1985? Population 1: April p = 795/1528 = 0.5203 Population 2: May p = 840/1528 = 0.5497 Show all your steps, setting up your null and alternative hypothesis.
For a one-sample test for a population proportion pp and sample size nn, why is it necessary that np0np0 and n(1−p0)n(1−p0) are both at least 10 ? A)The sample size must be large enough to support an assumption that the distribution of the population is approximately normal. B)The sample size must be large enough to support an assumption that the distribution of the sample is approximately normal. C)The sample size must be large enough to support an assumption that the sampling distribution of the sample proportion is approximately normal. D)The sample size must be large enough to support an assumption that the observations are independent. E)The sample size must be large enough to support an assumption that the sample proportion is an unbiased estimator of the population proportion.
A ski lift manager is interested in the average daily number of ski lift users. In previous years, fewer than 945 people, on average, have used the ski lift daily over the winter season. The manager suspects this average has increased in recent years. If the ski lift manager chooses to use the p-value approach for his hypothesis test, what does he need to compare the p-value to?
