Answer with explanation:</h2>
Let be the population mean.
Null hypothesis :
Alternative hypothesis :
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic:
Critical t-value for t=
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.
To calculate the distance between two points, you have to use the distance formula.
point 1 is (-5, -8) and point 2 is (-1, -16). The x coordinate is before the comma and the y coordinate is after the comma.
The distance formula is:
Distance =
Insert your coordinates into the formula.
Combine your terms.
Square your numbers.
Add these terms together.
Your answer is or 8.94
