The t-statistics that will ba calculated from the data about the steel housing will be -5.936.
<h3>How to calculate t-statistic?</h3>
From the information given, the component part of the housing is a steel trough that is made out of a 14-gauge steel coil.
From the complete question that has the data, the t-statistic will be calculated thus:
u = 8.46
x bar = 8.422
s = 0.04
n = 49
Therefore, the t-statistics will be:
= (8.421 - 8.46) / (0.046 / ✓49)
= -5.936
In conclusion, the t-statistics is -5.936.

The statement which best describes the effect of high altitude on climate is: temperatures are lower.
A climate can be defined as the long-term average atmospheric conditions (weather) that is prevailing in a geographical region and persists for a very long period of time.
Generally, some of the factors that affect the climate of a geographical region include the following:
According to meteorologist, an effect of high altitude on climate is that the <u>temperatures</u> in the particular geographical region are <u>lower</u>, especially due to the height of this region above sea level.
In conclusion, an effect of high altitude on climate is colder temperatures in a particular geographical region.
