Answer:
will you let me off the hook because of my cute pika pfp?
19. 19.31 times 40=$772.4
20. 52 times 772.4=$40,164.8
weekly = 40 times 19.31
yearly =weekly times 52 or 19.31 times 40 times 52
21. 15.07 times 40=$602.8
22. 52 times 602.8=$31,345.6
weekly = 40 times 19.31
yearly =weekly times 52 or 15.07 times 40 times 52
23. Monica yearly-Chris yearly=40,164.8-31,345.6=$8816.2
Answer:
yes
Step-by-step explanation:
Answer:
Step-by-step explanation:
For the null hypothesis,
µ = 60
For the alternative hypothesis,
h1: µ < 60
This is a left tailed test
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 100,
Degrees of freedom, df = n - 1 = 100 - 1 = 99
t = (x - µ)/(s/√n)
Where
x = sample mean = 52
µ = population mean = 60
s = samples standard deviation = 22
t = (52 - 60)/(22/√100) = - 3.64
We would determine the p value using the t test calculator. It becomes
p = 0.00023
We would reject the null hypothesis if α = 0.05 > 0.00023
0.25kgx9.81 then u will get the ans.
