Answer:
Kindly check explanation
Step-by-step explanation:
(a)
H0 : μ = 12
H1 : μ > 12
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
(b)
H0 : μ = 10
H1 : μ > 10
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
(c)
H0 : μ = 100
H1 : μ < 100
This is a left tailed test ; the alternative hypothesis has a less than sign, difference between sample and population mean value will be negative.
(d)
H0 : μ = 12
H1 : μ > 12
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
Answer:
Step-by-step explanation:
1 - V = (l(w)h)/3 = (14·9.5·15)/3 = 665ft^3
2 - 73.5ft^3 C
3 - (8·8·12)/3=256in^3
4 - (1.5·2·4)/3 = 4cm^3
5 - (12·6·9)/3=216in^3
Answer:
(8,4)
Step-by-step explanation:
y and -y cancels out leaving you with "12x=96"
that simplifies to "x=8"
Then you substitute 8 into the "x" from either equation and y should equal 4
