We expect the risk of a hospital to change by.0070695 for each change in the number of beds and that result is significant at the.01 level. b. An increase in the number of beds is associated with an increase in hospital risk at the.10 significance level. O c. Beds are a significant predictor of risk at the.05 level. d. Beds are not a significant predictor of risk at the.01 level

Answer 1

p-value of beds = 0.0095 < 0.01

if p-value < alpha

then variable is significant .

option C) is correct

coefficient = 0.0070695

when variable is changed by 1 unit, y changes by coefficient .

hence option A) is correct

since coefficient > 0

option B) is also correct

option A),B) and C) are correct
