Fiona wrote the predicted and residual values for a data set using the line of best fit y=3.71x-8.85. Which statements are true

about the table? Select three options. The data point for x = 1 is above the line of best fit. The residual value for x = 3 should be a positive number because the data point is above the line of best fit. Fiona made a subtraction error when she computed the residual value for x = 4. The residual value for x = 2 should be a positive number because the given point is above the line of best fit. The residual value for x = 3 is negative because the given point is below the line of best fit.

He takes a random sample of 49 recent charterholders and computes a mean salary of $172,000 with a standard deviation of $35,000
uysha [10]

Answer:

the 90% of confidence intervals for the average salary of a CFA charter holder

 (1,63,775 , 1,80,000)

Step-by-step explanation:

<u>Explanation</u>:-

random sample of n = 49 recent charter holders

mean of sample (x⁻) =  $172,000

standard deviation of sample( S) = $35,000

Level of significance α= 1.645

<u> 90% confidence interval</u>

(x^{-} - Z_{\alpha } \frac{s}{\sqrt{n} } , x^{-} + Z_{\alpha } \frac{s}{\sqrt{n} })

(172000 - 1.645 \frac{35000}{\sqrt{49} } , 172000 +1.645 \frac{35000}{\sqrt{49} })

on calculation , we get

(1,63,775 , 1,80,000)

The mean value lies between the 90% of confidence intervals

(1,63,775 , 1,80,000)
