To ensure that the pizzas being produced are roughly 10 inches, she samples 30 pizzas at random every hour starting at 9 am until 4 pm and measures the diameter of these pizzas using a ruler. That means, every work day, she collects 8 samples with 30 pizzas each and inspects these 240 pizzas. Which of the statement (s) is true?

a) n equals 8

b) n equals 30

c) The number of samples is 8

d) The sample size is 30

e) The sample size is 8.

f) Each day she collects a total of 240 observations.

g) n equals 240

h) The sample size is 240.
