the company claimed that every​ 18-ounce bag of their chocolate chip cookies contained at least 1000 chocolate chips. Dedicated statistics students at a school purchased some randomly selected bags of cookies and counted the chocolate chips. Some of their data are given below. ​a) Check the assumptions and conditions for inference. Comment on any concerns you have. ​b) Test their claim by performing an appropriate hypothesis test.   1216 1215 1096 1187 1429 1118 1333 1342   1241 1247 1355 1132 1195 1272 1306 1130 What is the test statistic t=?? what is the p- value= ??

Conduct a hypothesis testing, write down all relevant statistics and parameters check conditions and calculate testing. Test at a 5% significance level. Base your answer on a classical or p vaule approach

In Exercises, hypothesis tests are proposed. For each hypothesis test, a.identify the variable.b.identify the two populations.c.determine the null and alternative hypotheses.d.classify the hypothesis test as two tailed, left tailed, or right tailed. Driving Distances. Data on household vehicle miles of travel (VMT) are compiled annually by the Federal Highway Administration and are published in National Household Travel Survey, Summary of Travel Trends. A hypothesis test is to be performed to decide whether a difference exists in last year’s meanVMTfor households in the Midwest and South

A certain statistics instructor participates in triathlons. The accompanying table lists times​ (in minutes and​ seconds) he recorded while riding a bicycle for five laps through each mile of a​ 3-mile loop. Use a 0.05 significance level to test the claim that it takes the same time to ride each of the miles. Does one of the miles appear to have a​ hill?   LOADING...

Best on-time airlines: Hawaiian Airlines topped the list of the most punctual U.S. airlines for full-year 2014, according to data released by the Bureau of Transportation Statistics. The on-time arrival performance was 91.9% Another aviation data service believes that this percentage now is even higher. The team of researchers chose 130 randomly selected flights and find that 120 of the flights arrived on time. Can a hypothesis test be used to determine whether the proportion of Hawaiian Airlines flights that arrive on-time is higher than 91.9%?  Yes, because the sample is random. Thus, it is representative of the population of flights for the airlines.  Yes, because the sample is random and (130)(0.923) and (130)(0.077) are both at least 10. This means the normal model is a good fit for the sampling distribution.  Yes, because the sample is random and (130)(0.919) and (130)(0.081) are both at least 10. This means the normal model is a good fit for the sampling distribution.

Hypothesis Test: Perform the specified hypothesis test. Be sure to include your statistical andin-context conclusion statements. In 1994, 52% of parents with children in high school felt it was a serious problem that high schoolstudents were not being taught enough math and science. A recent survey found that 512 of 1000 parentswith children in high school felt it was a serious problem that high school students were not being taughtenough math and science. Do parents feel different today than they did in 1994? Use the α = 0.005significance level.

Information about a sample is used to make a prediction about the population. This type of statistical analysis is referred to as: Descriptive Statistics Mathematical Certainty Deductive Reasoning Inferential Statistics Sampling Statistics

A De Anza student decided to determine whether the percent of men who participate in sports at De Anza College is higher than the percent of women who participate in sports at De Anza College. Out of 67 women, 12 said they participate in sports. 13 of the 45 men surveyed said they participate in sports. a. ) What are the type I and type II errors? Explain them in the context of this problem.b. ) Describe the sample statistics in words. What is the distribution of the sample statistic? Explain why you used this distribution.Can someone please help me make sense of these questions?
