Need help with last part in the box. 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 attheir 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....What kind of test is this?Y One-proportion z testO Two-proportion t testO Difference in differences testO Proportional t testCheck 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 = 72.5 successes and ng, = 410.6 failures, which are both morethan 10.B. The 483 residents were a random sample from the county of interest. The sample size is more than 100. One expects np, =successes and ngo =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 npo =successes and nqo =failures, which are both more than 20.Thus, the conditions aremet and it isappropriate to use a Normal model and perform the hypothesis test.c) Draw and label a sketch, and then calculate the test statistic and P-value.Choose the correct sketch below.VA.O B.В.C.Q0.0870.100.150.0700.1500.2300.0070.0870.1670.0070.0870.167Calculate the test statistic.(Round to two decimal places as needed.)
