Answer:
The 99% confidence interval for the population mean is 22.96 to 26.64
Step-by-step explanation:
Consider the provided information,
A sample of 49 customers. Assume a population standard deviation of $5. If the sample mean is $24.80,
The confidence interval if 99%.
Thus, 1-α=0.99
α=0.01
Now we need to determine 
Now by using z score table we find that 
The boundaries of the confidence interval are:
Hence, the 99% confidence interval for the population mean is 22.96 to 26.64
Answer:
81.6
Step-by-step explanation:
4 × 22 + 16 ÷ 4 - (4.9 + 5.5)
88 + 4 - (10.4)
81.6
False, you only flip the inequality if you divide out a negative.
Answer:
I = 60 + 18k
Step-by-step explanation:
Data provided in the question:
The function for number of loaves, N that Moses bake
⇒ N(k) = 10 + 3k
here,
k is the kilograms of floor received
and,
Income in dollars, I(x) = 6x
here, x is the number of loaves baked
thus,
when k kilograms of flour is received,
x = N(k) = 10 + 3k
substituting x in income function,
we get
I = 6(10 + 3k)
or
I = 60 + 18k
Answer: y = -8x - 1
Step-by-step explanation: 2 x (-4) is -8. Therefore you get y = -8x - 1
