This is a follow up to the previous assignment you helped with.
•If the Economic Freedom scale is constructed in such a way that the population mean and standard deviation are 50 and 15 respectively, based on the sample data, the 90% lower confidence level of the sample mean is?a. 68.38b. 61.44c. 60.58d.59.83e.53.90The 95% confidence interval estimate for sample means of the variable "Life" is:a. 75.66 ± 2.12b. 75.66 ± 2.44c. 75.66 ± 2.47d. 75.66 ± 3.12•The proportion of females in the population of the various countries was not collected for this sample and is unknown. What would be a conservative estimate of the margin of error at a 95% confidence level for a sample of this size?a.± 0.204b.± 0.155c.± 0.130d.± 0.101

Also, using the same spreadsheet can you please compute the correlation matrix for the appropriate variables and determine their significance at 10%, 5% and 1% levels.
