NEED HELP ASAP TAKING TEST-On average, a person’s body temperature should be approximately 98.6°F. A doctor would like to test the hypotheses H Subscript 0 Baseline: mu = 98.6 versus H Subscript alpha Baseline: mu not-equals98.6 where μ = the true mean body temperature of all adults. Before conducting the test, the doctor determines that the power of the test to reject the null hypothesis when μ = 98 using α = 0.01 and n = 10 is 0.2474. What combination of sample size and significance level would increase the power of this test the most?
use n = 5, alpha = 0.05
use n = 5, alpha = 0.10
use n = 20, alpha = 0.05
use n = 20, alpha = 0.10
answer: 20
step-by-step explanation:
c. y = 1/4 x + 5
step-by-step explanation:
first, put the equation of the line on the graph into slope-intercept form
(y = mx + b): y = -4x + 8
second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )
original slope: m = -4 perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)
new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
step-by-step explanation :
we know that
the measurement of the outer angle is the semi-difference of the arcs which comprises
in this problem
m< xzy is the outer angle
substitute the values
the measure of angle xoy is equal to
> by central angle
substitute the value
