That is very cool and rare if you did it nice job!
Answer: Correct critical value = 2.2622
Step-by-step explanation:
Confidence interval for population mean when population standard deviation is unknown:
, where 
= sample mean, n= sample size, s= sample standard deviation, 
= two-tailed t value.
As per given: n= 10
degree of freedom : df = n-1=9
Critical t-value : 
So, the 95 percent confidence interval estimate for the mean :
The 95 percent confidence interval estimate for the mean:(190.14, 295.06)
3/4 divided by 1/5 = 3 3/4
Hope that helps :)
Solution:
we have been asked to find
Which of the given number words represents the numeral 4,056?
Its about the counting.
On unit place we have 6.
on Tenth place we have 5.
on hundredth place we have 0.
On Thousand place we have 4.
so in our number word representation there will be no "Hundreds".
So it will make
Hence the given number words representing the numeral 4,056 is Four thousands and fifty six
H = hrs she worked
p = phone calls she answered
h x 10 + p x .25 = maggies earnings
Part A
h x 10 + 60 x .25 = 115
Part B
h x 10 + 15 = 115 (multiplied 60 x .25)
h x10 = 100 (subtracted 15 from each side of the equation)
h = 10 (divided 10 into each side)
Part C
10 hrs
Hope this helps
