Answer:
Standard error for the distribution of means = 0.4474
Step-by-step explanation:
Standard error for the distribution of means is given as
σₓ = σ/√n
where σ = standard deviation = 2.237
n = sample size = 25
σₓ = (2.237/√25)
σₓ = 0.4474
Hope this Helps!!!
1. I want to know what percent of the school has birthdays in the summer
2. A form with the months of the year listed, so each participant can just circle the month they were born in. I’d have pencils and a form collection box.
3. I would give the form to every fifth student to leave the cafeteria on one day. I will count up how many forms were completed and how many forms have a summer birth month circled. Then I can find the percentage of students surveyed who have summer birthdays.

I think what they’re looking for it is for you to get information that reflects a part of a larger group of students.
Statistics always wants a randomized sample, giving everyone an equal chance to be surveyed and/or represented in the survey. Getting the survey done in one day, on people leaving the cafeteria, where everybody has to go at some point in a day, and choosing every fifth person keeps you from showing any bias to who you’re surveying.
Please comment if you have questions about this, or if your teacher asks for more information.
