(1 Points) Question 10: A population is known to be normally distributed with o = 17.88. A sample of 13 scores randomly selected from the population was found to have a mean of m = 69. Calculate the lower limit of the 85% (1 Points) confidence interval about m. 4 Question 11: According to the null hypothesis, a sample of 7 scores was drawn from a normal population with a mean of 1986 and a standard deviation of 28. If the sample mean is 1988, calculate p for Zobs (1 Points) assuming H1: H1 - Ho
