Answer:

Between 15.5 and 16.5 ounces

Step-by-step explanation:

If the distribution is bell-shaped it follows a normal distribution.

In a normal distribution you except the 95% of the values between +-2 standard deviation from the mean.

$Limits\ for\ 95\%: \mu\ \±\ 2\sigma$

lower limit = 16 - 2 * 0.25 = 15.5

upper limit = 16 + 2 * 0.25 = 16.5
