- The following data presents the productivity scores of 10 workers before and after acertain training program designed to improve productivity. Higher scores indicate better productivity. Do these data provide sufficient evidence that the training program has improved productivity? Perform a hypothesis test at the 5% significance level.We want to assess the relationship between class rank and how many minutes a person spends on social media. We randomly select 5 students from UMD and have them report their class rank and number of minutes per week they spend on social media. We get the following data. Because class rank is ordinal data, we want to compute Spearman's rho. Please compute the numerator for Spearman's rho and use 4 decimal places for all computations and final answer. (the numerator is referring to the numerator of the fraction, not including the 1- part) Minutes on Social Class Rank Media per Week 100 1,302 500 25 250 10 600 50 200Why is chi squared being found for 1-alpha and not 1-alpha/2
- From the Pearson r coefficient -0.63 compute for the coefficient of determination then interpret.You said the P-value is 0.995339, if that is the p-value, why arent we multiplying 0.995339 by 2 instead of 0.004661? Are you assuming that the p-value 0.995339 is for the left-tail and if so why?Modified True or False VIF values that exceed 10 are generally viewed as evidence of the existence of problematic errorterms
- In this question, the real numbers in your answers should be given with three significant digits of accuracy after the decimal point. The public health authorities of a small town have divided the population into three categories: covid- negative, covid-positive, and hospitalised. After performing regular, extensive tests, they have observed that in each successive week: Among those who are negative, 95% remain so, 4% become positive, and 1% need to be hospitalised. • Among those who are positive, 75% recover and become negative, 20% stay positive, and 5% need to be hospitalised. Among those who are hospitalised, 60% recover and become negative, 30% are released from hospital but remain positive, and 10% remain hospitalised. (a) After representing the population in a given week as a column vector v = [n; p; h], where n, P, and h represent the number of people in the population who are negative, positive, and hospitalised respectively, write down a matrix M for which [n', p', h'] = M[n;…If the coefficient of determination between two independent variables is 0.33, what is the VIF? VIF= (Round to three decimal places as needed.)Suppose P(A) = 0.59, P(B) = 0.28, and P(An B)= 0.01. What is P(Aª|B)? [Give your numeric response to at least 3 decimal places. Give only the number, and no extra characters or symbols.]
