A market research company is studying the effectiveness of two workout
products intended to help beginners maintain a workout habit over a longer
period of time. They define success rate as the proportion of all new users who are
still actively using the product after 6 months. A sample of 565 users of the first
product has 307 who are still active after 6 months, and a sample of 513 users of
the second product has 278 who are still active after 6 months.
At 5% significance, can the market research company conclude that there is a
difference in the true success rates?
Yes
No
