SCENARIO 2: In Spring 2020, a sample of 522 World Campus students were surveyed and asked if they own a dog. Of the 522 students in the sample, 273 said that they did have a dog. Referring to Scenario2, the sample proportion to estimate the population proportion is O a. 1.233 O b. 0.025 O c. 0.477 O d. 0.523 Referring to Scenario2, in order to use normal approximation procedure, the condition must be satisfied is O a. np =10 and n1-p=10 O b. np =10 and n1-p=0 O c. np =0 and n1-p=10 O d. np =0 and n(1-p)=0
