Answer:
d) t = -10.12
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given sample size 'n'=10
Given the differences of mean x⁻ -μ = -3.36
Standard deviation of the sample 'S' =1.05 inches
We will use t-statistic
t = -10.12
Tan(44) = X/140 (X is the height of the pole prior to adding the 4 foot stand)
X = Tan(44) (140)
X = about 135
Add the remaining 4 from the stand
About 139 feet. (<- Your Answer)
Which makes sense considering a 45-45 triangle has same side lengths, and 44 is very close to 45, therefore the pole length will be very similar to the distance the person walked.
Answer:
magnitude of decrease = 120 - 54 = 66$
the percentage = (66/100)×100 = 66%
