Determine if this test is left-tailed, right-tailed, or two-tailed. Oleft-tailed Oright-tailed Otwo-tailed Should the standard normal (2) distribution or Student's (t) distribution be used for this test? O The standard normal (2) distribution should be used O The Student's t distribution should be used Determine the critical value(s) for this hypothesis test. Round the solution(s) to four decimal places. If more than one critical value exists, enter the solutions using a comma-separated list. Determine the test statistic. Round the solution to four decimal places. Determine the appropriate conclusion for this hypothesis test. O The sample data do not provide sufficient evidence to reject the null hypothesis that the mean time spent gaming per week by adult gamers is 421 minutes per week and thus we conclude that it is likely the true average time spent gaming by adult gamers is 421 minutes per week. O The sample data do not provide sufficient evidence to reject the alternative hypothesis that the mean time spent gaming by adult gamers is different than 421 minutes per week and thus we conclude that the mean time spent gaming per week by adult gamers is likely different than 421 minutes. O The sample data provide sufficient evidence to reject the alternative hypothesis that the mean time spent gaming by adult gamers is different than 421 minutes per week and thus we conclude that the mean time spent gaming per week by adult gamers is likely 421 minutes. O The sample data provide sufficient evidence to reject the null hypothesis that the mean time spent gaming per week by adult gamers is 421 minutes per week and thus we conclude that it is likely the true average time spent gaming by adult gamers is different than 421 minutes per week.
