Please solve for the single sample using t test and find the t value. A sample of psychology students in MSU-IIT was part of a study that examined their happinesslevel using a 9-point Likert scale. The mean from a previous study on the happiness level of thegeneral population of MSU-IT was 6.4. Determine whether the current sample has significantlyhigher levels of happiness as compared to the general population of MSU-IIT students. These arethe scores of the sample: 8, 4, 6, 3, 6, 5, 8.Significance level = .05

The lengths of adult males' hands are normally distributed with mean 187 mm and standard deviation is 7 mm. Suppose that 18 individuals are randomly chosen. Round all answers to 4 where possible. DO NOT USE EXCEL FORMULA. CALCULATE BY HAND OR CALCULATOR. 1. For the group of 18, find the probability that the average hand length is more than 189. 2. Find the third quartile for the average adult male hand length for this sample size.

Please do not give solution in image formate thanku. I am looking for help with the following question: A large distributor just received a shipment of 1000 cartons of egg. Each carton has 12 eggs and the carton is up to standard if the weight of that carton (total weight of 12 eggs) is more than 28 oz. Previous shipment shows that 96% of the egg cartons are up to standard. In this sampling problem, the setup cost to sample additional units are negligible since the weighing station is readily available whereas it does take time and resource to weigh the carton and record the data. How many cartons should one sample if one wants to estimate the proportion of up to standard egg cartons to within 1% with 99% confidence? a. If you use educated guess. b. If you use conservative method? c. Do you expect that this sample size from educated guess would guarantee the resulting confidence interval being as short as specified? Explain briefly. d.
