2. Compute the value of the test statistic. z=______
3. Determine the critical value(s).
4._________ the null hypothesis. At the 10% significance level, the data____________sufficient evidence to conclude that adult females are ___________ the RDA of iron, on average.
Answer:
Step-by-step explanation:
Given that the recommended dietary allowance (RDA) of iron for adult females is 18 milligrams (mg) per day. The given iron intakes (mg) were obtained for 45 random adult females.
1)
(left tailed test at 10% sigl level)
Mean difference = -3.35
2) Test statistic Z = Mean difference/std error =-5.35
3) Critical values are -1.28
Since critical value is > test statistic accept H0
4) ___Fail to reject______ the null hypothesis. At the 10% significance level, the data_____shows_______sufficient evidence to conclude that adult females are ____equal to 18 mg_______ the RDA of iron, on average.
Answer:
D, or the last answer
Step-by-step explanation:
First, plugin the value of y into the equation, resulting in 12 - 2(-2) = 8.
Second, Simplify as much as you can on the left hand side of the equation, resulting in 12 - (-4), and because of the double negative rule, those two negatives become a plus. 16
Lastly, see if the two sides are equal or not equal. 16 is NOT equal to 8. That means D is your answer.
b t>w
C not possible to tell
Given the values sin(t) = 0.45 and sin(w) = 0.89, both for angles in the first quadrant, we can determine that the angle w is greater than the angle t. This is because in the first quadrant, the sine of an angle increases as the angle increases.
The sine of an angle in the unit circle, sin(t) or sin(w), is the y-coordinate of the point where the angle intersects the unit circle. The angles are in quadrant 1, where sine values are positive, as are the angles themselves. Given sin(t) = 0.45 and sin(w) = 0.89, we know that the sine of an angle increases as the angle increases within the first quadrant (from 0 to 90 degrees). Therefore, sin(w) > sin(t) implies that w > t.
