scoundrel [369]

Answer:

92.65 % light bulbs last less than 2080 hours

Step-by-step explanation:

We are given that The amount of time a certain brand of light bulb lasts is normally distributed

Mean = $\mu = 2000$

Standard deviation = $\sigma = 55$

We are supposed to find What percentage light bulbs last less than 2080 hours, to the nearest tenth

$Z = \frac{x-\mu}{\sigma}\\\\Z=\frac{2080-2000}{55}$

Z=1.45

Refer the z table for p value

p value = 0.9265

Hence 92.65 % light bulbs last less than 2080 hours
