answer 1, 2, and 3

Activity 1.4. Determine the minimum sample size for each of the following: 1. 95% confidence level, E = 4.8, 0-30 2. 96% confidence level, E = 5, o=45 3. 99% confidence level, E = 8.5, 0-55 4. A random sample of size 70 was used with a population standard deviation of 15. Assuming that there is a 92% confidence level, what is the margin of error? 5. Compute for the appropriate sample size needed if the margin of error is 15, with a population standard deviation of 43 and a 98% level of confidence.
