What we are looking for is the confidence interval.
Given:
Sample it is denoted by n = 10
Mean = 80
Standard deviation = 12
Confidence Interval = 99%
Now compute for the margin of error, the formula is Za/2 * σ/√(n)
A 99% level of confidence has a critical value of zα/2 = 2.58.
The standard error is σ/√(n) = 3.162
Multiply 2.58 by 3.162 = 9.8 is the margin of error.
The formula for confidence interval is x̅ ± Za/2 * σ/√(n)
= 80 ± 9.8
= 70.2 < x< 89.8

Explanation:
The complete statements of the given sentences are-
- Orange juice has a viscosity lower than chocolate syrup.
- There are strong attractive forces between atoms of liquids with a high viscosity.
- Surface tension is the result of water molecules pulling inward with strong force.
Viscosity refers to the measurement of a fluid's thickness. As a result, a liquid with a high viscosity is thicker than one with a low viscosity.

Answer:
pizza establishment.
Explanation:
Based on the scenario being described within the question it can be said that in this situation the conditioned stimulus is the pizza establishment. That is because a conditioned stimulus is neutral stimulus that triggers a conditioned response after it has been associated with an unconditioned stimulus. Therefore in this scenario the conditioned stimulus is the pizza establishment which causes Vanessa to feel sick every time she sees it (conditioned response).
