Answer:
Step-by-step explanation:
From the table of function given, you would observe that if you subtract 2 from half of the x-variable values, you'd get the y-variable values.
For example, half of -8 = -4. If you add 2 to -4, you'd get: -4 + 2 = -2. Same applies to other x-values on the table.
Thus, an expression for the function represented by the table values can be written as,
Answer: 0.9730
Step-by-step explanation:
Let A be the event of the answer being correct and B be the event of the knew the answer.
Given:
If it is given that the answer is correct , then the probability that he guess the answer
By Bayes theorem , we have
Hence, the student correctly answers a question, the probability that the student really knew the correct answer is 0.9730.
Answer:
a
The estimate is
b
Method B this is because the faulty breaks are less
Step-by-step explanation:
The number of microchips broken in method A is
The number of faulty breaks of method A is
The number of microchips broken in method B is
The number of faulty breaks of method A is
The proportion of the faulty breaks to the total breaks in method A is
The proportion of the faulty to the total breaks in method B is
For this estimation the standard error is
substituting values
The z-values of confidence coefficient of 0.95 from the z-table is
The difference between proportions of improperly broken microchips for the two breaking methods is mathematically represented as
substituting values
The interval of the difference between proportions of improperly broken microchips for the two breaking methods is
