Given in the question that, We need to Interpret the value of $S{E}_b$in context .

In order to answer the topic, researchers looked at how nature manages the size of animal predators that destroy a bigger proportion of the population when prey density is low. The amount of perch in a confined region is the explanatory variable, and the proportion of perch killed by bass in two hours while bass have access to the perch is the response variable. A scatterplot is provided, which depicts a linear relationship. Also included is a residual graphic for the least square regression line. For this data, the computer output is provided. The standard deviation of the slope is supplied in the row with "Perch" and the column with "Stdev.":${\mathrm{SE}}_b$

${\mathrm{SE}}_b=0.002456$

This indicates that the slope is steep.

We need to interpret the interval from part (b) in context.

In order to answer the topic, researchers looked at how nature manages the size of animal predators that destroy a bigger proportion of the population when prey density is low. The amount of perch in a confined region is the explanatory variable, and the proportion of perch killed by bass in two hours while bass have access to the perch is the response variable. A scatterplot is provided, which depicts a linear relationship. Also included is a residual graphic for the least square regression line. For this data, the computer output is provided. As a result, it is stated,

$n=16$

$b=0.008569$

${\mathrm{SE}}_b=0.002456$

The sample size was reduced by two degrees of freedom:

$df=n-2$

$=16-2$

$=14$

In table$\mathrm{t}$, the critical $\mathrm{B}$-value can be located in the row of $df=14$and the column of $c=90\%$as

$t^{*}=1.761$

As a result, the confidence interval is as follows:

$b-t^{*}脳{\mathrm{SE}}_b$

$=0.008569-1.761脳0.002456$

$=0.004244$

$b+t^{*}脳{\mathrm{SE}}_b$

$=0.008569+1.761脳0.002456$

$=0.012894$

Given in the question that, We need to interpret the interval from part (b) in context.

In order to answer the topic, researchers looked at how nature manages the size of animal predators that destroy a bigger proportion of the population when prey density is low. The amount of perch in a confined region is the explanatory variable, and the proportion of perch killed by bass in two hours while bass have access to the perch is the response variable. A scatterplot is provided, which depicts a linear relationship. Also included is a residual graphic for the least square regression line. For this data, the computer output is provided. As a result of portion (b),$(0.004244,0.012894)$

As a result, we have $90$percent confidence that the true slope of the population regression line is between $(0.004244,0.012894).$

Given in the question that, We need to explain the meaning of 鈥�$90\%$ confident鈥� in context.

In order to answer the topic, researchers looked at how nature manages the size of animal predators that destroy a bigger proportion of the population when prey density is low. The amount of perch in a confined region is the explanatory variable, and the proportion of perch killed by bass in two hours while bass have access to the perch is the response variable. A scatterplot is provided, which depicts a linear relationship. Also included is a residual graphic for the least square regression line. For this data, the computer output is provided. In this instance, "confident" means that the confidence interval will contain the correct value of the population parameter in $90\%$ of all available samples.
