If sampling distributions of sample means are examined for samples of size 1, 5, 10, 16 and 50, you will notice that as n increases in size, the shape of the sampling distribution appears more like that of the:

a. normal distribution

b. population distribution

c. uniform distribution

d. even distribution

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
