Natalie is in charge of inspecting frozen pepperoni pizzas. 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.

The statements that are true are:

b) n equals 30

c) The number of samples is 8

d) The sample size is 30

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

Step-by-step explanation:

She takes a sample every hour, so she takes 8 samples during the day.

Each samples consist of 30 individuals (pizzas).

This adds a total of 240 observations during the day.

The statements that are true are:

b) n equals 30

c) The number of samples is 8

d) The sample size is 30

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