Answer:
Check the explanation
Step-by-step explanation:
We have:
Null Hypothesis:
H o:μ = 215
Alternate Hypothesis:
Η α :μ> 215 This is a one tailed test
Standardized value to be tested:
== -= 1.93
Since this is a one tailed test, critical t value which occurs at 95% confidence level is 1.943.
Since 1.93 < 1.943, we can say that At α = 0.05, there is insufficient evidence to indicate that the mean price of all digital cameras exceeds $215.00.
To make it sufficient, we need value more than 1.943.
At α = 0.10, critical t value is 1.440 (less than 1.93) which makes it sufficient.
Answer:
One of the properties of triangle is the opposite of the largest angle is the longest leg and the smallest angle is opposite the shortest leg.
Given the three sides of the triangle with its corresponding angle, we have:
(2m+3) = m∠X
(m-3) = m∠Y
(m+8) = m∠Z
assign value for m; let m = 6
2(6)+3 = 15 = m∠X
6 - 3 = 3 = m∠Y
6 + 8 = 14 = m∠Z
As the sides correspond to its angle, therefore, the largest angle is m∠X and the smallest is m∠Y
The correct one is m∠Y < m∠Z < m∠X
