Answer:
z = 2.1784 > 1.96,
Reject the null hypothesis
Step-by-step explanation:
For the males:
n1 = 162, x1 = 63
P1 = x 1/ n1 = 0.3889
For the Females:
n2 = 333,
x2 = 97
P 2 = x2/n2
= 0.2913
P 1= P2 Null hypothesis
P 1 is not equal to P 2 alternative hypothesis
Pooled proportion:
P= (x1 + x2) /( n1+ n2)
= (63 + 97) / (162 + 333)= 0.3232
Test statistics :
Z= (p1 - p2) /√p(1-p)× (1/n1 + 1/n2)
0.3889- 0.2913 / √0.3232 × 0.6768 × (1/162 +1/333)
=2.1784
c) Critical value :
Two tailed critical value, z critical = Norm.S .INV (0.05/2) = 1.960
Reject H o if z < -1.96 or if z > 1.96
d) Decision:
z = 2.1784 > 1.96,
Reject the null hypothesis
B. 0 ÷ 28 = 0
Is the mathematical statement that is true.
Rule of ZERO. Zero(0) can be a numerator with non-zero denominator. Its overall value is equal to 0.
Rule of ZERO. A fraction with a denominator of ZERO is not a legal fraction. This is because the overall value of a number divided by zero is undefined.
28 + 0 = 28 not 0.
28 - 0 = 28 not 0.
28 ÷ 0 = ERROR! not 0. value is undefined
Answer:
| 2 | + | 4 | = 6
| − 3 | + | 5 | = 8
| − 7 | + | − 1 | − | 6 | = 2
Anything that is an absolute value is positive so you just add the numbers normally... even if the numbers are negative..
