Adata set includes 103 body temperatures of healthy adult humans for which x= 98.1 and s = 0.56.

a.) what is the best point estimate of the mean body temperature of all healthy humans?

the best point estimate is =

b.) using the sample statistics, construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. do the confidence interval limits contain 98.6?

what does the sample suggest about the use of 98.6 as the mean body temperature?

what is the confidence interval estimate f the population mean ? ? round to three decimal places. show work.

< ? <

do the confidence inteval limits contain 98.6?

98.1, No does not contain, yes contains.

Step-by-step explanation:

Given that

sample size n =103

Sample mean = 98.1

sample std dev s = 0.56

a) the best point estimate of the mean body temperature of all healthy humans = sample mean =98.1

b) 99% confidence interval estimate of the mean body temperature of all healthy humans

We can use Z critical since sample size is large though sigma is not known

99% CI =

This does not contain 98.6

This sample does not represent the population, i.e. may be biased sample.

c) CI of population mean

= populaiton mean + /- margin of error

=(98.545, 98.656)

Yes contains 98.6

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
