For the problem in the picture I don't expect you to do the whole thing. If you could just state the null hypothesis and the alternate hypothesis that would be great each of the questions below please state the test statistic you used. For each problem you must a) state nullalternate hypotheses, b) calculate appropriate test statistic, c) evaluate hypothesis by calculating thepropriate test statistic and testing this value against the appropriate critical value, d) provide details on a., thetical value, and DF, f) provide biological conclusion.A genetics engineer was attempting to cross a leopard and a Maltese or blue tiger. She predictecenotypic outcome of the traits she was observing to be in the following ratio 4 stripes only: 3 spotsonly: 9 both stripes and spots. When the cross was performed and she counted the individuals she foun57 with stripes only, 38 with spots only and 82 with both. According to the Chi-square test, did she getthe predicted outcome?

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.

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.

Hi, I am doing a project on hypothesis testing. I've been struggling a lot with understanding it. I added two pictures. One has the data set I'm working with and what I thought would be a good hypothesis to test. The second photo is all the questions I have to complete. I tried to do the null and alternative hypotheses. I'm not sure if these are right though. If you could help, I would really appreciate it. Thank you

A car manufacturer claims that its latest model can average 60 miles per gallon on the highway - and an auto magazine's editor wants to put that claim to the test. (a) Write the null hypothesis for this situation. (b) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is lower than what's being claimed. (c) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is simply different from what's being claimed.
You are a paranoid delusional statistician with far too much time on your hands. One day, you sit down to have a bowl of soup. This bowl of soup happens to be Tic-Tac-Toe themed, meaning that you have some noodles that are shaped like an X, and some that are shaped like an O. As you stir your soup, you notice that this bowl seems to have a particularly high number of X- shaped noodles in it. Being paranoid, you conclude that this has some meaning like someone is trying to give you a message, possibly warning you of the dangers of x-rays. You jump out of your seat and run to get your x-ray-proof cape, and then you pause for a moment and think that you should calculate a chi-square statistic for the frequency of X-shaped noodles before freaking out. First, you carefully separate each of the noodles by shape and count them. Here is what you find: Frequency of Noodles X-shaped 33 O-shaped 21 2. Write out the null and alternative hypotheses using symbols: Но: На:
H1: This is a homework question. I chose a Null Hypothesis that is equal to the Alternative because the professor is comparing the two formats. Is my reasoning correct? Would this be a directional question? A statistics professor is interested in finding out whether students perform better on exams if they are conducted in the classroom or online. He compares the final exam scores of his online statistics class with the exam scores of his in-person class. What is the null hypothesis for this scenario? Null Hypothesis: final exam scores in class = final exam scores online Alternative Hypothesis: final exam scores in class is NOT Equal to final exam scores online
You watch people exiting Dodgers stadium after a game and you write down the number of males and the number of females that exit the stadium past you during the 20 minutes that you spend watching. You assumed that there would be a perfectly equal number of males and females attending a Dodgers game, but you look at the number of males and females that you actually counted, and you see if you still think that is actually true. What kind of hypothesis test would allow you to do this? a. One-Factor, Independent-Measures ANOVA b. Two-Factor ANOVA c. Correlation/Regression d. Chi-Square Goodness of Fit
A hospital claims that the proportion of full-term babies born in the hospital who weigh less than seven pounds is no more than 42%. Suppose that we want to carry out the hypothesis test for this claim, suspecting otherwise. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test.
