Kenya is a behavioral psychologist who works with children on the Autism Spectrum. She suggests that blowing bubbles may effect children's eye contact (she hasn't predicted if it would increase or decrease). She works with a student who makes 5 points of eye contact in a session. How would the NULL hypothesis be state for her study using bubbles? µ < 5 µ = 5 µ > 5 µ ≠ 5
2. You carry out a test of the hypothesis described in #1. If the results show that you cannot reject the null hypothesis, what conclusion can you generate based on your claim?
Bonus Problem: For each situation, decide whether the null hypothesis should be rejected. (a) α = 0.01, P-value = 0.047, (b) α = 0.01, P-value = 0.15.
These are previous year papers that i want to solve before the start of next semester. Can you please help me solve these? A new drug has been developed to treat cancer. It is of interest to know whether the low dose (X1 = 0) or high dose (X1 = 1) will be better for cancer patients. There are 60% of patients randomly assigned to high dose.For this question, if asked to do a hypothesis test, please include the following:1. The formula of the test statistic,2. the reference distribution with degrees of freedom and the conditions for the test statisticto follow this reference distribution,3. plug in the numbers from the R output into the test statistic. You do not need to simplifythe expression,4. state when will you reject or fail to reject the hypothesis. a)Write out the linear regression model of Y (a continuous measure of tumor size) on dose X1 using low dose as reference level.b) The r output of the regression model from part 1 is given below. Fill in the blanks. Call:lm(formula = Y…
QUESTION 4 Assume you are conducting a hypothesis test to determine if pesticides cause cancer in rural areas. The hypotheses are: The null hypothesis is no cancer. The alternate hypothesis is cancer. Select if the result for Box B is correct, a Type I error, a Type Il error or if there is insufficient information to make the decision. *****Read the labels very carefully. Но: по сапсer Ha: cancer Reality: Reality: Null is true Alternate is true (i.e. no cancer) (i.e. cancer) Decision: Accept the null hypothesis (i.e. test is negative for cancer) A B
Let’s assume the average income for all majors in the School of Engineering is $80,000. However, the chair of the Computer Science department thinks their students earn more than that. Please choose the appropriate null and alternative hypotheses if the chair wanted to test this belief. a. H0: u <=80,000 Ha: u > 80,000 b. H0: u= 80000 Ha: u not= 80000 c. H0: u >80000 Ha: u < 80000 d. H0: u >80000 Ha: < 80000 e. None of the above.
I need help understanding the null hypothesis and when to “reject” or “fail to reject” it. I got 5.77 in 3df and a critical value of 7.82.
A random sample of 500 adult residents of Maricopa County found that 361 were in favor of increasing the highway speed limit to 75 mph, while another sample of 400 adult residents of Pima County found that 292 were in favor of the increased speed limit. Do these data indicate that there is a difference in the support for in increasing the speed limit between the residents of the two counties? Use a = 0.05. (a) Test the hypothesis Ho: P₁ = P2 versus H₁: P₁ P2. What is zo? Round your answer to two decimal places (e.g. 98.76). Zo = (b) Is it reasonable to conclude that there is a difference in the support for increasing the speed limit between the residents of the two counties?
why are large x2 values sometimes obtained when the null hypothesis true?
The solution for H0 or H1 was not given or explained in the expert solution provided.
My lawn needs mowing , but i do not want to mow if its going to start raining while I'm in the middle of the job. So i am looking at the sky evaluating the weather, using the null hypothesis: "It will rain within the next two hours". In this situation , what would a type I error be?
