The mean of 15 sample iq scores of statistic instructors is 118. the sample standard deviation is 11. given the sample data appear to come from a normally distributed population, find the test statistic for a claim that the population mean iq of statistic instructors is greater than 110.

t = 10.909

t = 2.817

t = 9.342

t = 3.767

t = 2.817

Step-by-step explanation:

The test statistic for testing a claim that the population mean IQ of statistic instructors is greater than 110 will be the student's t test statistic since;

The sample data appear to come from a normally distributed population and the the population standard deviation is not know.

The following information has been availed;

The sample size = n = 15

The sample mean of IQ scores = 118

The sample standard deviation = s = 11

The following hypothesis is to be tested;

Null hypothesis : Population mean = 110

Alternative hypothesis : population mean > 110

The test statistic is determined through the standardization of the sample mean;

t = 2.8167

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
