Construct a 99% confidence interval to estimate the population mean using the accompanying data. What assumptions need to be made to construct this interval? x=51
ơ= 17 n= 18
What assumptions need to be made to construct this interval?
A. The sample size is less than 30
B. The population mean will be in the confidence interval.
C. The population must be normally distributed
OD. The population is skewed to one side.
With 99% confidence, when n = 18, the population mean is between the lower limit of and the upper limit of
(Type an integer or decimal rounded to two decimal places as needed.)

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
