Answer:
see below
a = 0.66...
b = 0.73
c = 7/8
Step-by-step explanation:
The first two numbers, 0.73 and 0.667, are near the point that is halfway between 0.6 and 0.8. That halfway point is 0.7. The value 0.667 will be below (left) of the halfway point, so is point <em>a</em>. The value 0.73 will be above (right) of the halfway point, so is point <em>b</em>. The remaining value, 7/8, must be point <em>c</em>.
__
You may know that 7/8 = 0.875, so is nearly halfway between 0.8 and 1.
_____
The attached graph has the points color-coded.
_____
Of course you know that the overline in indicates that digit repeats indefinitely. The value 0.667 is the number rounded to 3 decimal places.
We have the sample size, sample mean and the sample standard deviation. Since the population standard deviation is not know, we will use t-distribution to find the confidence interval.
The critical t value for 95% confidence interval and 63 degrees of freedom is 1.998.
The 95% confidence for the population mean will be:
Thus, the 95% confidence interval for the population mean will be (115,123)
So, option A is the correct answer
The critical t value for 95% confidence interval and 63 degrees of freedom is 1.998.
The 95% confidence for the population mean will be:
Thus, the 95% confidence interval for the population mean will be (115,123)
So, option A is the correct answer
The exact x and y coordinate of the point of intersection is (-1.84, 6.792)
