The true option about the randomized design is (c) Betty should prepare all 60 cookies.
Each cookie will receive a number.
The numbers will be written on slips of paper, put into a hat, and shuffled well.
The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.
The given parameters are:
n=60
batches=4
cookies=15 ---- the number of cookies in each batch
Temperature=300,325,350,375.
To randomly assign the cookies to the given temperatures, all cookies have to be subjected to the same conditions (except for the difference in the temperature).
<h3>What is the temperature?</h3>
Normal human body temperature is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37 °C. Human body temperature varies.
This means that she can bake all the cookies at once at different temperatures while noting down the cookies with a given number.
Hence, the true option is (c)
