I need help with part b the null and alternative hypotheses for both H0 and H1 please The accompanying information is a set of coded experimental data on the compressive strength of a particular alloy at various values of the concentration of some additive. Complete parts (a) and (b) below.Click the icon to view the compressive strength data.(a) Estimate the quadratic regression equation µyx = ßo +ß₁×₁ +ß₂×².ŷ= 19.19 + ( 0.994) ×₁ + ( − 0.020 ) ×³₁(Round the constant to two decimal places as needed. Round all other constants and coefficients to three decimal places as needed.)(b) Test for lack of fit of the model.State the null and alternative hypotheses.HoH₁An exponential model would fit the data better than a quadratic model.There is no lack of fit for the model.There is a lack of fit for the model.A linear model would fit the data better than a quadratic model.A cubic model would fit the data better than a quadratic model.

PLS ANSWER THESE FOUR QUESTIONS THEY BASICALLY GO HAND AND HAND WITH EACH OTHER
Give the null and the alternative hypotheses for the following situations. You only need to set up the hypotheses in this part. Make sure to use the appropriate parameter symbol in the statement of the hypotheses: p or µ. The null and alternative hypothesis has been given for the first problem. 1. A coffee manufacturer sells jars of coffee supposedly filled with 10 ounces of coffee. The Consumer Fraud Bureau of a state has received numerous complaints that some of the jars contain less than the specified 10 ounces. The Bureau decides to investigate these complaints by sampling 100 jars. Does the data indicate that the coffee manufacturer can be accused of "short-changing" the customer? Use a 5% level of significance. Ho: Ha: 2. . In an ABC/Washington Post survey 855 randomly selected Americans listed gun control as an important issue in elections. Can ABC and the Washington Post claim that this survey provides sufficient evidence to say that a majority of Americans consider…
Which of the following is an improper form of the null and alternative hypotheses? H₂H SH and H₂> Ho Ho: =Hand H₂H40 Ho
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.
A recent study at a university showed that the proportion of students who commute more than 15 miles to school is 25%. Suppose we have good reason to suspect that the proportion is greater than 25%, and we carry out a hypothesis test. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho: 0 H;: D O
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 don't know which part I get wrong but I only have 6/10. Could you check my answer please
11. The null and alternative hypotheses For each pair of hypotheses that follows, decide whether H₀ and H₁ are set up correctly as the null and alternative hypotheses for a hypothesis test. If so, select “Valid” from the drop down menu. If not, select “Invalid”. 1 H₀: μ = 76 2 H₀: M = 234 H₁: μ ≠ 76 H₁: M ≠ 234 Invalid 3 H₀: μ = 16 4 H₀: µ = 112 H₁: μ ≠ 16 H₁: µ ≠ 111 You evaluate the by assuming that it is true and testing the reasonableness of this assumption by calculating the probability of getting the results if chance alone is operating.

It's just one question with sub-parts. Since you are only allowed to do 3 questions please do D, E, F the last 3 only. Thank you
The first picture is the question and the second is the ones that need help with. Just B,C,DThanks!
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
