A quality control engineer at a potato chip company tests the bag filling machine by weighing bags of potato chips. Not every ba

g contains exactly the same weight. But if more than 10% of bags are over-filled then they stop production to fix the machine. They define over-filled to be more than 1 ounce above the weight on the package. The engineer weighs 153 bags and finds that 41 of them are over-filled. He plans to test the hypotheses H 0 : p = 0.1 versus H a : p > 0.1. What is the test statistic? z = (Please round your answer to two decimal places if necessary.)

Step-by-step explanation:

Given in the question a logarithm expression

7^(log_{49}16 )

We will use Exponent of Log Rule

b^(log_{b}k ) = k

here b = 7

        k = 16

So suppose

7^(log_{49}16 ) = x\\Take square on both sides\\(7^(log_{49}16 ) )^{2} = x^2\\49^(log_{49}16)= x^2

Now, according to the rule

16 = x²

to find x only take square root on both sides of the equation

x = √16

x = 4

so 7^(log_{49}16 ) = 4
