Respond to the question with a concise and accurate answer, along with a clear explanation and step-by-step solution, or risk receiving a downvote. You are interested in studying the relationship between class size and test scores. Past researchhas suggested that smaller classes lead to better student outcomes. You have decided to testthis hypothesis. To do so, you have collected data on 22 students at SDSU. You have data onstudent GPA, and the average class size for the student.You estimate the following regression:GPA,= Bo + Bi Class Size + €₁You get the following results:bo= 4.000b₁ = .020SE = 1.230SE = 0.010What is the 99% confidence interval for the slope parameter b₁? Use Table D. Note that thedegrees of freedom will be n-2. Round your answer to the third decimal point.-0.0200.010O-0.020+0.015-0.0200.028-0.0200.021

To calculate the 99% confidence interval for the slope parameter, we use the formula:CI = b₁ ±…

ARTICLE/PROBLEM: The Fisher's folks harvested 9.25 tons of milkfish in 20 cages in a day. The leader of the folks decided to harvest the remaining 10 cages to come up with an additional harvest with 7 in the tenths place and 3 in the hundredths place that leads to a total harvest less than 15 tons but more than 14 tons in two days. INSTRUCTIONS: Read the given problem. Then answer the following: QUESTIONS: What will be possible harvest of the Fisher's folks in two days? What is the place value and value of number 3? YOUR CLAIM: Cite from the article two evidences that support your claim: EVIDENCE 1: EVIDENCE 2: Explain how your evidences support your claim. REASONING:
2 Mouldy home. A landlord is deciding whether to undertake routine maintenance on their rental property to reduce the potential for damp/mould issues. The weather throughout the year could turn out to be mostly dry, moderately wet, or extremely wet. Without routine maintenance, the cost of damage to the property and lost rental income is $500 in a mostly dry year, $2000 in a moderately wet year, and $8000 in an extremely wet year. Routine maintenance will cost $1200 and reduces the cost of damages and lost income to $0 in a mostly dry year, $400 in a moderately wet year, and $2400 in an extremely wet year. (a) Construct the payoff table for this decision which describes the total costs. (b) Calculate the EMVS for the two decisions ("No Maintenance", "Maintenance") if the probabilities of mostly dry, moderately wet and extremely wet are 0.25, 0.6 and 0.15, respectively. (c) What would be a sensible objective in this scenario and, based on your calculations, what should the landlord do?
more than one option is the answer. So what else could it also be along with option c?

What I Can Do Read the situation carefully and solve the problem. The new COVID-19 testing facility in Lucena City is operating with two laboratory technicians. Technician A takes 2 hours to finish 50 samples of specimens from COVID-19 patients. Technician B takes 3 hours to finish 45 samples of specimens from COVID-19 patients. Working together, how long should it take them to finish 150 samples of specimens from COVID-19 patients? Hint: Think about how many samples of specimens each technician can finish in one hour. This is their testing rate.

You have been named the Good Reader in your town’s reading club. You’re invited to give a 15-minute speech at the annual reception. You want to spend the speech talking about three themes; (1) how you came to love books, (2) the camaraderie you feel in the club, and (3) your long-term goals for encouraging reading in the town. You would like to spend at least 2 minutes talking about each theme. How many ways can you segment your time so that you talk enough about each theme? Note that you should assume the number of minutes you spend talking about each theme is a natural number. One example of a valid breakdown is 3 minutes on theme 1, 5 minutes on them 2, and 7 minutes on theme 3. Describe how you arrived at your solution.
