1 answer:
Answer:
The diagonal distance across the plaza is 7141.8 meter. Step-by-step explanation:
Given : Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 5050 meters.
To find : What is the diagonal distance across the plaza?
Solution :
We have given the side of a square a=5050 m
The length of the diagonal is multiply the length of square with square root 2.
Substitute the value of a in the diagonal formula,
Nearest tenth = 7141.8 m
Therefore, The diagonal distance across the plaza is 7141.8 meter.

Answer:
Test statistic = -2.25
P-value = 0.0199
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 450 gram
Sample mean, = 441 grams
Sample size, n = 16
Alpha, α = 0.05
Sample variance = 256
First, we design the null and the alternate hypothesis
We use one-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Degree of freedom =
We can calculate the p-value from the table as:
P-value = 0.0199
Conclusion:
Since the p-value is smaller than the significance level we fail to accept the null hypothesis and reject it.
Thus, there is enough evidence to support the claim that the machine is under filling the bags .
