Find the equation of the regression line for these data. What is the
value of the standard error of the estimate? Place your answer,
rounded to 3 decimal places, in the blank. Do not use a dollar sign.
For example, 0.345 would be a legitimate entry.

Accepted characters: numbers, decimal point markers (period or
comma), sign indicators (-), spaces (e.g., as thousands separator, 5
000), "E" or "e" (used in scientific notation). NOTE: For scientific
notation, a period MUST be used as the decimal point marker.
Complex numbers should be in the form (a + bi) where "a" and "b"
need to have explicitly stated values.
For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid
whereas {9i} is not.
An investor wants to compare the risks associated with two different
stocks. One way to measure the risk of a given stock is to measure the
variation in the stock’s daily price changes.
In an effort to test the claim that the variance in the daily stock price
changes for stock 1 is different from the variance in the daily stock
price changes for stock 2, the investor obtains a random sample of 21
daily price changes for stock 1 and 21 daily price changes for stock 2.
The summary statistics associated with these samples are: n1 = 21, s1
= .848, n2 = 21, s2 = .529.
