Pick the correct null hypothesis using the flowchart H0 and H1

The manager at a social work agency is interested in whether providing standardized case file forms to her social workers can LESSEN the number of errors the social workers make in filling out their case file paperwork. In the general population of all social workers at this firm, the average number of errors per case file is u = 2.3 errors, while the sample of social workers using the new standardized forms makes an average of M = 1.8 errors per case file. She plans to test this using a One-Sample Z-Test with one tail, a = .01. Hint: Don't even look at the options below until you have fully written out HO and H1 on your own using the flowchart!! Then all you have to do is find the option that matches your answer. a) Herrors # 2.3 b) Herrors = 1.8 C) Herrors $ 2.3 d) Herron # 1.8 e) Herrors > 2.3 f) Herrors > 1.8 g) Herrors 2 2.3 h) Herrors 2 1.8 i) Herrors $ 2.3 j) Herrors 2.3 () standardized forms > 1.8 s) |standardized forms 2 2.3 t) Hstandardized forms 2 1.8 u) standardized forms
