Answer:
<h2>10.7%</h2>
Step-by-step explanation:
Step one:
given
expected weight= 28pounds
Actual weight= 25 pound
Required:
percent error
![\delta = \left| \frac{v_A - v_E}{v_E} \right| \cdot 100\%](https://tex.z-dn.net/?f=%5Cdelta%20%3D%20%5Cleft%7C%20%5Cfrac%7Bv_A%20-%20v_E%7D%7Bv_E%7D%20%5Cright%7C%20%5Ccdot%20100%5C%25)
δ= percent error
vA =actual value observed
vE =expected value
δ=25-28/28*100
δ=-3/28*100
δ=0.107*100
δ=10.7%
The percent error is 10.7%
Answer:
Kindly check explanation
Step-by-step explanation:
The power of a test simply gives the probability of Rejecting the Null hypothesis, H0 in a statistical analysis given that the the alternative hypothesis, H1 for the study is true. Hence, the power of a test can be referred to as the probability of a true positive outcome in an experiment.
Using this definition, a power of 90% simply means that ; there is a 90% probability that the a Pvalue less Than the α - value of an experiment is obtained if there is truly a significant difference. Hence, a 90% chance of Rejecting the Null hypothesis if truly the alternative hypothesis is true.
