Answer:
We conclude that her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company states.
Step-by-step explanation:
We are given;
Population mean; μ = 30 minutes
Population standard deviation; σ = 3 minutes
Sample size; n = 10
Sample mean; x¯ = 25
Significance level = 5% = 0.05
Let's define the hypotheses;
Null hypothesis; H0: μ = 30
Alternative hypothesis: Ha: μ ≠ 30
Let's find the test statistic;
z = (x¯ - μ)/(σ/√n)
z = (25 - 30)/(3/√10)
z = -5.27
From online p-value from z-score calculator attached using, z = -5.27, significance level = 0.05, two tailed hypothesis, we have;
p < 0.00001
This is less than the significance level, and so we will reject the null hypothesis and conclude that Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
Answer: The answer is (B) 58 + 360n, for any integer 'n'.
Step-by-step explanation: We are given to select the correct expression that represents the measures of all angles co-terminal with an angle of measurement 418°.
Co-terminal Angles are angles who share the same initial side and terminal sides.
We can find co-terminal angles by simply as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.
Therefore, if 'n' is an integer, then all the co-terminal angles with 418° angle is given by
Thus, the correct option is (B).
