Ozone (O3) is a major component of air pollution in many cities. Atmospheric ozone levels are influenced by many factors, including weather. In one study, the mean percent relative humidity (x) and the mean ozone levels (y) were measured for 120 days in a western city. Mean ozone levels were measured in ppb. The following output (from MATLAB) describes the fit of a linear model to these data. Assume that the required assumptions are satisfied sufficiently well that we can do the usual analysis.>> fitlm(Humidity, Ozone)Linear regression model: y ~ 1 + x1Estimated Coefficients:Estimate SE tStat pValue (Intercept)29.7240 2.051 14.490 0.0000x1 -0.1268 0.03825 -3.315 0.0006Number of observations: 120, Error degrees of freedom: 118 Root Mean Squared Error: 6.26 R-squared: 0.960, Adjusted R-Squared 0.890(a) What is the slope of the least-squares line?(b) Find a 95% confidence interval for the slope.(c) Perform a test of the null hypothesis that the slope is equal to β0.1.

Jace wrote a sentence as an equation. 56 is 14 more than a number. 14+ = 56 which statement best describes jace's work? jace is not correct. the phrase more than suggests using the symbol > and jace did not use that symbol. jace is not correct. he was correct to use addition, but the equation should be 56+ p = 14 jace is not correct. the first number in the sentence is 56, so the equation should start with 56. jace is correct. the phrase more than suggests addition, so jace showed that 14 plus a variable equals 56. o
