If we wish to have a 95% confidence level, what would be the value of α?& Determine the value of the confidence coefficient z(α/2) for the situation below:​1 − α = 0.95

1.) If we Wish to have a 95% confidence level, What would be the value of a? Value of a = 100%-95%=5% (the answer to alpha=5%) 2)To do this problem, you need z-table.If 1- alpha = 0.90, alpha…
