1. Harden College is contemplating opening a European campus where students from the main campus could go to take courses for 1 of the 4 college years. At themoment, it is considering five countries: Holland, Great Britain, Italy, Belgium, and Greece. The college wishes to consider eight factors in its decision. The first twofactors are given weights of 0.2, while the rest are assigned weights of 0.1. The following table illustrates its assessment of each factor for each courntry (5 is best).Candidate Country RatingsFactor Critical Success FactorsHolland Great BritainItalyBelgiumGreeceStability of governmentDegree to which the population canconverse in English34.3535.24.Stability of the monetary systemCommunications infrastructureTransportation infrastructureAvailability of historic / cultural sites444.44.4.4.4.4.7.Import restrictions448.Availability of suitable quarters52a) Based on the given information, the best country for Harden College to locate the new campus iswith a total weighted score of (Enter yourresponse rounded to one decimal place)

A survey was conducted to assess the preference of people to reopen LA economy after the extended lockdown due to Corona. Out of 340 males questioned 230 wanted to open the economy and 110 did not. Out of 290 females questioned 218 wanted to open the economy and 72 did not. Can we say that the two factors, gender and preference to open the economy, are related? Use alpha = .05.
The Widington College program is considering buying a Scanner machine among 5 (five) types, namely the SC1, SC2, SC3, SC4 and SC5 types, where each type has different efficiency in terms of the speed of the number of pages (sheets) scanned in one minute. Six staff members conducted an experiment to run each type of scanner. The following data shows the number of scanned pages (sheets) that can be produced in one minute according to the type of copier, 1 trial, and according to the staff assigned to run each type of scanner: SC 1 SC 2 SC 3 SC 4 SC 5 Staff 1 60 50 63 60 64 Staff 2 56 55 65 58 60 Staff 3 54 56 65 56 58 Staff 4 56 57 67 65 60 Staff 5 54 56 65 60 60 Staff 6 55 52 58 60 55 Some of the results of the calculation of the sum of squares (sum-square) and the average squared (mean square) required for the ANOVA test are provided in the following table: Source of Variation SS Df MS F stat F Table Scanner Machine 333.3 ..... ..... ..... .....

An industrial-organizational psychologist believes that implementing a 2-hour lunch break at US companies will have an effect on employee productivity. On a productivity scale from 1 to 15, the average productivity score for all companies in the US is 8 (u = 8.00, ỡ = 4.00). The IO psychologist randomly samples 5 companies and has the companies implement a 2-hour lunch break for 1 month. At the end of the month, the lO psychologist measures the productivity scores for the five companies and obtains the following scores: 9, 14, 10, 12, 15 Using the appropriate hypothesis test and the six steps of hypothesis testing, determine what the 10 psychologist should conclude about the effect of a 2-hour lunch break on employee productivity. 1) What are the null and alternative hypotheses 2)Construct a sampling distribution of means representing the null hypothesis. Specify the sampling distribution's mean and standard error 3)Using a two-tailed alpha of .05 (a = 05), determine the critical…

A manufacturing company that produces laminate for countertops is interested in studying the relationship between the number of hours of training that an employee receives and the number of defects per countertop produced. Ten employees are randomly selected. The number of hours of training each employee has received is recorded and the number of defects on the most recent countertop produced is determined. The results are as follows. Hours of Training Defects per Countertop 1 5 4 1 7 0 3 3 2 5 2 4 5 1 5 2 1 8 6 2 Copy Data The estimated regression line and the standard error are given. Defects per Countertop=6.717822−1.004950(Hours of Training)se=1.229787se=1.229787 Suppose a new employee has had 5 hours of training. What would be the 90% prediction interval for the number of defects per countertop? Round your answer to two decimal places.
