Solve thes problem - Speech or foundation ExampleFrom a table, the probability of a value being to the left or equal 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 world under the curve will be shaded when the endpoints be 2.5758 standard deviations away from the mean. The endpoints for this confidence interval are found byAdding a prototype 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 in spite of appearance the needed range.To calculate the probability that Type 1 error occurs, we want to calculate what is the probability that the zero point hypothesis is correct ( the p-value is greater than .05 significance level) and the mean of the sample is in one of the tail ends 12.This would final result in an interval (6.9 to 13.1). The p robability that there is a Type 1 error when the original rejection criteria is use mean 12, is the probability that the mean falls within the intervals 6.9 to 8 and 12 to
