Hence, the z value at the 95 percent confidence interval is 1.96.Let us consider the third case for which the given confidence level is 99 percent. In this case too, we need to calculate the area under the curve and it can be given as shown in the figure belo...
true. In general, a p-value less than 0.05 is considered to be statistically significant, in which case the null hypothesis should be rejected. This can somewhat correspond to the probability that the null hypothesis value (which is often zero) is contained within a 95% confidence interval. ...
