Step-by-step explanation:
Assuming the data is as shown, restaurant X has a mean service time of 180.56, with a standard deviation of 62.6.
The standard error is SE = s/√n = 62.6/√50 = 8.85.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
180.56 ± 1.960 × 8.85
180.56 ± 17.35
(163, 198)
Restaurant Y has a mean service time of 152.96, with a standard deviation of 49.2.
The standard error is SE = s/√n = 49.2/√50 = 6.96.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
152.96 ± 1.960 × 6.96
152.96 ± 13.64

The energy of an electromagnetic wave is typically emitted in short bursts referred to as photons.
<h3>What is electromagnetic energy?</h3>
Electromagnetic energy can be defined as form of energy that is primarily carried by electromagnetic waves such as:
This ultimately implies that, an electromagnetic energy refers to a form of energy that typically moves as particles at the speed of light, which is about three hundred million meters per seconds (3 × 10⁸ m/s).
In conclusion, we can infer and logically deduce that the energy of an electromagnetic wave is typically emitted in short bursts referred to as photons.

- <em>A solid is a sample of matter that retains its shape and density when not confined, A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity.</em>
I hope this gives you some sort of assistance.
Reread the textbook just to make it better <em>(if you can quickly look through it)</em>
Anyways goodluck!
