6. Assume you want to construct a 98% confidence interval with a sample of n-10 from ofa nomally distributed population. Find the critical value ta2 (1 point) 2764 02.821 0 1.383 O3.250 7. A sample of size n - 12 does not have a known population standard deviation. The population (1 point) appears to be normally distributed. Determine whether a margin of error should be calculated using a critical value of za2, a critical value of t, or neither. a...
