According to a recent study, college students own a mean of 6.9 technological devices. (laptops, smartphones, etc.).2Karen conducts a SRS of 60 college students and finds that her sample has a mean of x¯= 5.2 technological devices. Conduct a hypothesis test at the α = 0.01 level to determine if you can conclude that the mean number of technological devices owned by college students is less than 6.9. Assume that σ = 5.6 devices. Round the standard error to the nearest thousandth
