Solve thes problem - Speech or Presentation ExampleFrom a table, the probability of a value being to the left or cost to this z-score is .8962 so the probability to be to the right of z = 1.2649 (or to the left of z = -1.2649) isFor 99% confidence intervals, 99% of the area under the curve will be shaded when the endpoints are 2.5758 standard deviations away from the mean value. The endpoints for this confidence interval are found byAdding a sample size m = 75, find the sample mean (m2) of the added sample that would lead to a p-value 0.05 for the combined sample. Find the probability of obtaining a sample mean from the added sample within the needed range.To calculate the probability that lineament 1 error occurs, we want to calculate what is the probability that the null hypothesis is correct ( the p-value is greater than .05 significance level) and the mean of the sample is in one of the lav ends 12.This would result in an interval (6.9 to 13.1). The probability that there is a Type 1 error when the original rejection criteria is used mean 12, is the probability that the mean go within the intervals 6.9 to 8 and 12 to
