Need help trying to solve and understand this step by step for review?

Hypothesis Testing For each of the following find the Null and alternate hypothesis, find the critical test statistic and graph, then use the data to find the test statistic, decide to reject or fail to reject the null hypothesis, write an informative script about the conclusion, and if the z-chart was used find the pvalue and com pa re that to alpha. 1.) A travel analyst claims that the mean price of a round trip flight from New York City to Los Angeles is less than $507. In a random sample of 55 round trip flights from New York City to Los Angeles, the mean price is $502. Assume the population standard deviation is 5111. At a! = 0.05, is there enough evidence to support the travel analyst's claim? 2.) After the collapse of the two World Trade Center buildings, there was a considerable concern about the quality of the air. Use a 0.05 significance level to test the claim that the sample is from a population with a mean greater than the EPA standard of 1.5 %. (The unit expressed in the problem is a microgram per cubic meter and does nothing to affect your calculation). Consider the following sample data to come from a population that is normally distributed. Show the work getting the sample mean and standard deviation. 5.4 1.10 0.42 0.73 0.48 1.10 3.) An interesting and popular hypothesis is that individuals can temporarily postpone their death to survive a major holiday or important event such as a birthday. In a study of this phenomenon, it was found that there were 6062 deaths in the week before Thanksgiving, and there were 5938 deaths the week after Thanksgiving. If people can postpone their deaths until after Thanksgiving, then the proportion of deaths in the week before should be less than 0.5. Use a 0.05 significance level to test the claim that the proportions of deaths in the week before Thanksgiving is less than 0.5. Based on the results does there appear to be any indication that people can temporarily postpone their death to survive the Thanksgiving holiday? 4.) In complete sentences (not just the definition) explain what the Type 1 and Type 2 error is for the following proportional statement. The proportion of murders cleared by arrest is 0.62. Type 1 error: Type 2 error
