- To carry out the lack or lack of fit test, it is necessary to partition the sum of squares due to random error in two: a. One due to the fitted model and one due to the pure error b. One due to lack of fit and one due to the fitted model c. One due to the total variation of the experiment and another due to the estimated model d. One due to lack of fit and one due to pure error Explain clearly each option pleasefind out probabilityof z score between -2.23 and 2.25In a study of starting salaries for assistant professors, five male assistant professors from three types of doctoral institutions were randomly surveyed; Their starting salaries were recorded but their names were kept anonymous.

- A company's quality engineer wants to check whether the average weight of the products coming out of the packaging line does not exceed 10 grams. For this, he measured the weights of the products coming out of the line by making random selection. Measurement values respectively; 8, 11,9,11,9,7,11,10,10,9. After a while ; A press machine with a newer technology has been replaced by a press machine where product losses are frequently experienced in the packaging line. and products with the same features were weighed after being processed in this new pressing machine. After the new pressing machine, the weights of the products were measured as follows; 8,8,13,17,8,12,16,14,13,15. a) Test whether the average weight of the products currently exceeds 10 grams or not, at a = 0.05 significance level, by writing the relevant hypotheses and applying all necessary steps to make a decision.
