Answer:
The 95% confidence interval is
This interval means that there 95% confidence that the true mean is within this interval
Yes i would agree with my friend because the lower and the upper limit 95% confidence interval for mean points scored at home is greater than 98 points
Step-by-step explanation:
From the question we are told that
The sample size is n = 20
The sample mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically evaluated as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the margin of error is mathematically represented as
substituting values
The 95% confidence interval is mathematically represented as
substituting values
The slope can be found using rise over run
the line goes up 5 and over 10
so the slope would be 5/10 or 1/2
therefore the equation of the line is:
y=1/2x
Answer:
Diameter is the width = 7.64 ft
Step-by-step explanation:
Perimeter would need to be the arc of a semi circle measuring less than or equal to 12 Where perimeter therefore = 12* 2 = 24 24 / 3.14 = 7.64331210191 where 3.14 the value for pi and formula of a semi circle we use radius = 1/2 pi * 3.82 ^2 = D * pi = 7.65 and radius =7.64 / 2 = 3.82 so answer is the diameter = 7.64 ft
Answer:
-7
Step-by-step explanation:
16-23=-7 because 23 is bigger than 16 so its going to end in a negative.
