Answer #1

The probability that of getting a head when a fair coin is tossed is 0.5.

The events of tossing a coin are independent. This means that the probability of getting head or tail when a coin is tossed is not dependent on the outcome of the previous toss.

Hence, on the fifth trial, the probability that head appears is 0.5

    Step 1: You tossed a coin 50 times and got 21 heads. The proportion of heads is pˆ= 21/50 = 0.42. The proportion is less than 0.5. You want to find out whether this is evidence that your coin is not balanced. Step 2: What conclusion can you make about this coin? o Because the chance of observing 21 heads in 50 tosses is large, we do not reject H 0 and conclude the coin is balanced. o Because the...
