Express the null hypothesis and the alternative hypothesis in symbolic form: An entomologist writes an article in a scientific journal, which states that fewer than 7 in 10,000 male fireflies are unable to produce light due to a genetic mutation. Use the parameter p, the true proportion of fireflies that cannot produce light. Obtain a simple random sample of 50 adults and half each person's red blood cell count (in cells per microliter). The sample mean is 5.23 and the sample standard deviation is 0.54. significance of 0.01 to test the claim that the sample is from a population with a mean less than 5.4. Based on the above situation, calculate the value of the test statistic. 3.- How to carry out a study correctly? Formulate the stated conclusion in non-technical terms. Be sure to address the original assertion: A researcher claims that 62% of voters are in favor of gun control. Assuming that a hypothesis test has been performed and that the conclusion is contrary to the null hypothesis, state the conclusion in non-technical terms. 4.- A buyer wants to compare the cost (in dollars) of airline tickets purchased one day in advance with those purchased 30 days in advance for flights from New York (JFK) to San Francisco by various airlines. Use a significance level of 0.01 to test the claim that scheduled flights one day in advance cost more than scheduled flights 30 days in advance. A computer program is used and the value of p = 0.0016 is found. What can be said about the sample (dependent or independent) and what can be concluded about the evidence?
