A survey is conducted to test whether the proportion of employees who prefer remote work is lower among those in manufacturing compared to those in technology. Out of 210210 manufacturing employees, 9898 prefer remote work. Out of 390390 technology employees, 312312 prefer remote work. At a 0.010.01 significance level, use randomization and bootstrapping to test the claim that the remote work preference rate is lower in manufacturing than in technology.

Problem 50Multiple Choice

A survey is conducted to test whether the proportion of employees who prefer remote work is lower among those in manufacturing compared to those in technology. Out of $210$ manufacturing employees, $98$ prefer remote work. Out of $390$ technology employees, $312$ prefer remote work. At a $0.01$ significance level, use randomization and bootstrapping to test the claim that the remote work preference rate is lower in manufacturing than in technology.

There is strong evidence that manufacturing employees are more likely to prefer remote work than technology employees.

Both methods provide statistically significant evidence that remote work preference is lower in manufacturing than in technology.

The randomization test shows no significant difference, but bootstrapping does.

Neither method shows a statistically significant difference in remote work preference.
