A normal phone user is spending an average of 220 Minutes per day, we speculate that those who are aged 41 - 56 use less, we have the following theorem H0: μ = 220 min Ha: μ < 220 min Below is other use full info Mean = 205, sd = 63.25 and size = 31 Answer the following estimate the population mean time spent using apps for 41 - 56 smartphone users. A) μ = 220 minutes B) x̄ = 220 minutes C) E(X) = 220 minutes D) μ = 205 minutes E) x̄ = 205 minutes F) E(X) = 205 minutes G) N/A Repeating the study man
