Answer:
Test is Left tailed test
Parameter tested is standard deviation
Step-by-step explanation:
We are given the hypothesis as;
Null hypothesis; H0: σ = 8.6
Alternative hypothesis; H1: σ < 8.6
Where;σ is a constant generally known in statistics as the standard deviation.
Now, it's the alternative hypothesis that will let us know whether this is left tailed, right tailed or two tailed.
Alternative hypothesis says σ < 8.6.
This means that the values of σ that satisfy this hypothesis are less than 8.6 and thus are on the left hand side of 8.6 on a number line. Thus, the shaded region in a normal distribution curve will be on the left.
Thus, it's a left tailed test

The equation that models the data on pandas is FV = 25(1.066)^t.
<h3>What models the data?
</h3>
The formula for calculating future value of the pandas is:
FV = P (1 + r) ^n
- FV = Future value
- P = Present value
- R = annual population growth
- N = number of years
FV = 25(1.066)^t

Answer: rectangles are congruent if both of them have the opposite sides are equal
Step-by-step explanation: rectangles are congruent if both of them have the opposite sides are equal. Two squares are congruent if both of them have the same edges.
Answer:
87%
Step-by-step explanation:
- 88.5% + 90% + 82% + 94.5% + 80% = 435%
- 435% ÷ 5 = 87%
- So, Lindsey's final average is 87%
I hope this helps!
