Consumer Reports tested a random sample of front-loading washing machines and top-loading washing machines to see if top-loaders were faster at washing a load of clothes. Their alternative hypothesis was where  = average time (in minutes) to wash one load of laundry.  Their sample statistic was not significant at the .05 level, so they were unable to conclude that on average, top loading machines were faster at washing a load of laundry than front-loaders.

Based on the decision reported, which error couldhave been made?

Type I

Type II

Both errors could have been made

It's impossible to know without more information.
