Answer:
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
I think it would be b) because you're given a slope of 0, so that leaves you with

, resulting into this

You'd be just left with a continuous horizontal line going through the y-axis of 3 since you're passing the point (2,3), where 3 represents the y-value when your slope is at 0.
Known :
r = 5 cm
θ = 360° - 90° = 270°
Asked :
Arc length of the partial circle = ...?
Answer :
Arc length

So, the arc length of the partial circle is 23,55 cm

Answer:
The p value for this case would be given by"
For this case since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean is significantly different from 6.5 lbs/square inch at 10% of significance. So then there is not enough evidence to conclude that the valve does not perform to the specifications
Step-by-step explanation:
Information given
represent the sample mean
represent the population deviation
sample size
represent the value that we want to test
represent the significance level
z would represent the statistic
represent the p value for the test
Hypothesis to verify
We want to verify if the true mean for this case is equal to 6.5 lbs/square inch or not , the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
And replacing we got:
The p value for this case would be given by"

Step-by-step explanation:
(12x - 19y) (12x + 19y) = 144x^2-361y^2
