question 38

Multiple Choice

Doctors at a technology research facility randomly assigned equal numbers of people to use computer keyboards in two rooms. In one room a group of people typed a manuscript using standard keyboards, while in the other room people typed the same manuscript using ergonomic keyboards to see if those people could type more words per minute. After collecting data for several days the researchers tested the hypothesis $\mathrm { H } _ { 0 } : \mu _ { 1 } - \mu _ { 2 } = 0$ against the one-tail alternative and found $P = 0.22$ . Which is true?

• A) There's a 22% chance another experiment will give these same results.
• B) none of these
• C) The people using ergonomic keyboards type 22% more words per minute.
• D) There's a 22% chance that there's really no difference in typing speed.
• E) There's a 22% chance that people using ergonomic keyboards type more words per minute.
