assume that research indicates that small children watch an average of 25hrs of tv per week. assume tv watching time is normally distributed and with alpha=3hrs. Randomly,select 20 children that,watch tv. calculate the probability that they will watch more than 26.3hrs of tv per week. ii)find the z value and p(z) value. 2) a sample has a mean of 93 and a standard deviation of 5.0, what raw score define the lower 15% of scores? ii) what raw score defines the upper 6% of scores? iii) what raw scores contain the middle 90% of scores?
