*ASSUMING THE ALPHA-LEVELS FOR THESE PROBLEMS IS .05.*
Step-by-step explanation:
8) Left-tailed test means that the alternate hypothesis is x is less than a certain value. The p-value, on the calculator, is normalcdf(-999, -1.83) if it's left-tailed, which is .0336. In that case, we would reject the null hypothesis, because the alpha-level is above our p-value.
9) Two-tailed test means that the alternate hypothesis is x does not equal a certain value. The p-value for this, on the calculator, is normalcdf(1.95,999) times two, because we need both tails. In this case, we would fail to reject the null hypothesis, assuming our alpha-level is .05.
- normalcdf(1.95,999) = .0256*2 = .0512.
Answer:
A. 871.97 m
Step-by-step explanation:
Model this is a <u>right triangle</u>.
Use the <u>sine trigonometric ratio</u> to find the height of the weather balloon from the ground.
<u>Sine trigonometric ratio</u>
where:
is the angle- O is the side opposite the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
- = 33°
- O = height
- H = 1601 m
Substitute the given values into the formula and solve for O:
Answer:
commutative property of multiplication
Step-by-step explanation:
This is something you have to be very careful of. This would not be considered associative because there are NO GROUPING SYMBOLS. This property ONLY applies to grouping symbols.
