Suppose there is a cdaim that a certain population has a mean, u, that is equal to 9. You want to test this daim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis H, and the alternative hypothesis H, as follows. Ho u=9 H p#9 Suppose you also know the following information. The critical values are -1.645 and 1.645 (rounded to 3 decimal places). The value of the test statistic is -2.281 (rounded to 3 decimal places).

A researcher is designing an experiment. Ultimately, she is hoping to reject her null hypothesis (i.e., show that the results of her experiment are statistically significant). What type of p-value would she want to obtain? 1. A large p-value. 2. A small p-value. 3. The size of a p-value has no impact on statistical significance.

You have a friend who needs your help with interpreting a statistical analysis. Your friend is starting out in a quality control job, and has some data involving weights of bags of a certain type of product. They wanted to test the null hypothesis that the true mean of bags of this type is 300 grams, against a two-sided alternative. Unfortunately, they are just starting out with R, and didn't quite understand the t.test command. They used the following command and found the following output. > t.test(bags) One Sample t-test data: bagst = 696.55, df = 39, p-value < 2.2e-16alternative hypothesis: true mean is not equal to 095 percent confidence interval: 309.1159 310.9164sample estimates:mean of x 310.0162 Without doing any calculations, help your friend out here. Explain to them what this output tells us about their desired test. (Suppose the weights are normally distributed, and that the sample of bags is a simple random sample from the population of interest.)

Please show your complete solution. Thank you! Please use Excel if possible. Problem: A sample of 800 items produced on a new machine showed that 48 of them are defective. The factory will get rid the machine if the data indicates that the proportion of defective items is significantly more than 5%. At a significance level of 5%, is there enough evidence to get rid of the machine? The following steps should be indicated in your answer: Null and Alternative Hypothesis (both in symbols and statement form) Level of Significance; sample size; test statistics Decision Rule Computation Decision and Conclusion
