Step-by-step explanation:

In an independent groups experiment, if we must estimate the population standard deviation to determine the significance of the sample results, the appropriate inference test is the<u> </u><u>t test</u>

<h3>For :</h3>
  • A t-test is one of the methods of a statistic and is used to determine if there is a significant difference between the two groups of their means based on a sample in data.  
  • The statistical significance is determined by the difference between the averages of group size , the sample size, and standard deviations of the groups.

Given the function f(x)=3^x, find the value of f^-1(27)
Shalnov [3]

This is asking you to solve the equation ...

... 27 = 3^x

You can use logarithms to find

... log(27) = x·log(3)

... log(27)/log(3) = x = 1.43136376.../0.47712125...

... x = 3

Or, you can use your knowledge of small cubes and match exponents.

... 3^3 = 3^x

... 3 = x

a jeweler buys a ring for $85.00 and sell it with 135% increase in price. How much did he sell it for?
siniylev [52]
Well if the increase is 135% then
actual price=85
135% of actual price=114.75
new price
= actual price + increased price
= 85+114.75
=119.75
