Spinning a coin, unlike tossing it, may not give heads and tails in equal proportions. I spin a penny 175 times and get 77 heads. We want to know if we have significant evidence that the coin is not fair.

• When we go to the One Proportion applet, what value should be entered under "Probability of heads" (or "Probability of success ")? Incorrect Round to 3 places.
• In the applet, what value should be entered under "Number of tosses" (or "Sample size (n)")?
• The simulated distribution of sample statistics will be centered at approximately what value when we click on "Proportion of successes"?
• The simulated distribution of sample statistics will be centered at approximately what value when we click on "Number of successes"? 175
