Check the appropriate conditions for a hypothesis test. Select the correct choice below and fill in the answer boxes within your choice. (Round to one decimal place as needed.) A. The 483 residents were a random sample from the county of interest. 483 is likely less than 10% of the population of a county. One expects npo = 61.65 successes and ngo = 349.35 failures, which are both more than 10. O B. The 483 residents were a random sample from the county of interest. The sample size is more than 100. One expects npo = 73.4 successes and ngo = 415.7 failures, which are both more than 10. OC. The 483 residents were a random sample from the county of interest. The standard deviation of p is less than 0.5. One expects npo = ngo = successes and failures, which are both more than 20.

Question

Need help with the boxed question.

According to a recent census, 15% of the people in the United States are of Hispanic origin. One county supervisor believes her county has a different proportion of Hispanic people than the nation as a whole. She looks at their most recent survey data, which was a random sample of 483 county residents, and found that 42 of those surveyed are of Hispanic origin. Complete parts (a) through (d) below. a) State the hypotheses. (The proportion of people in the county that are of Hispanic origin is denoted by p.) О А. Но: р2 0.15 О В. Но р30.15 На р<0.15 На: р<0.15 O C. Ho: p<0.15 HA: p= 0.15 D. H,: p= 0.15 HA: p#0.15 b) Name the model and check appropriate conditions for a hypothesis test. What kind of test is this? Y One-proportion z test O Two-proportion t test O Difference in differences test O Proportional t test Check the appropriate conditions for a hypothesis test. Select the correct choice below and fill in the answer boxes within your choice. (Round to one decimal place as needed.) O A. The 483 residents were a random sample from the county of interest. 483 is likely less than 10% of the population of a county.

One expects np, = 73.4 successes and ngo = 415.7 failures, which are both more than 10. O C. The 483 residents were a random sample from the county of interest. The standard deviation of p is less than 0.5. One expects np, = successes and ngo = failures, which are both more than 20
