Today due to COVID-19 virus pandemic in the USA, full-time college students report spending a mean of 20 hours per week on academic activities from home. Assume the standard deviation of time spent on academic activities is 3 hours. If you select a random sample of 50 full-time college students. Find the mean and standard deviation of the sampling distribution (the standard error) of "for a random sample of 50 full-time college students. Round standard error to four decimal places and use this rounded value for the rest of the question. Ⓒa.μ=2.8284 b.μ=2.8284 %=0.4243 C-A=20 d.μ=20 a=0.4243
