6) Make your own word problem of the form of this problem. Your word problem should apply directly to biology major. State the null and alternative hypotheses and alpha (α) . (Since you don’t have any data, you need not actually conduct the hypothesis test).
Please make a word problem stated above and answer all the parts based on the question below.

For the folowing claim, find the null and alternative hypotheses, test statistic, critical value, and draw a conclusion. Assume that a simple random sample has been selected from a normally distributed population. Answer parts a-d. Claim: The mean IQ score of statistics professors is less than 119. Sample data: n 11, x 117, s 14. The significance level is ?-005 Click the icon to view a table of critical t-values. a. Choose the correct null hypothesis (Ho) and altenative hypothesis...
Step 1 of 5: State the null and alternative hypotheses for the test. Ho: μd (=,≠,<,>,≤,≥) 0 Ha: μd (=,≠,<,>,≤,≥) 0 Step 2 of 5: Find the value of the standard deviation of the paired differences. Round your answer to two decimal places. Step 3 of 5: Compute the value of the test statistic. Round your answer to three decimal places. Step 4 of 5: Determine the decision rule for rejecting the null hypothesis H0H0. Round the numerical portion of...
Step 1 of 10 : State the null and alternative hypothesis. Step 2 of 10 : What does the null hypothesis indicate about the proportions of service calls received each day? Step 3 of 10 : State the null and alternative hypothesis in terms of the expected proportions for each category. Step 4 of 10 : Find the expected value for the number of service calls received on Monday. Round your answer to two decimal places. Step 5 of 10...
31. (4 points (bonus)) Use the following information to answer the question. A research company developed a drug to help lung cancer patients live longer. Without treat- ment, the average life expectancy for lung cancer patients is 3.2 months. The research company claim that their drug help cancer patients live longer. Suppose he does a hypothesis test with a significance level of 0.05. Symbolically, the null and alternative hypothesis are as follows: Ho: μ =3.2 and Ha: μ > 3.2....

A. B. Please follow the steps of hypothesis testing, including identifying the alternative and null hypothesis, calculating the test statistic, finding the p-value, and making a conclusions about the null hypothesis and a final conclusion that addresses the original claim. Use a significance level of 0.10. Is the conclusion affected by whether the significance level is 0.10 or 0.01?

Q7) A hypothesis test is to be performed with a Null hypothesis and an alternative hypothesis , the population standard deviation is σ=3.0, the sample size is 30, and the significance level is α=0.025. What is a type I error? (1 mark) What is the chance of making a type I error in the above test? (1 mark) What is a Type II error? (1 mark) What value would the sample mean have to be greater than to reject Ho? (2 marks) It is...
