Question

I want to explain this question to my classmates, but my English is not good.

I want to know how to explain this in sentence easily and fluently.

The first few months of 2020 were good for the stock market.

1- Gather a sample of 25 large open end funds year-to-date returns through January-March 16, 2020

(11.15, 6.82, 8.75, 9.40, 4.70) (19.5, 3.61, 5.51, 20.4, 22.1) (6.23, 4.32, 6.33, 5.62, 6.72) (7.04, 9.77, 5.24, 4.15, 7.81) (23.6, 4.24, 7.21, 5.73, 14.83)

2- What is the point estimate of the population mean year-to-date return for large open end funds?
3- Given that the population has a normal distribution, develop a 95% confidence interval for the population mean year-to-date return for open-end funds.
