Question

9. Males and females were asked about what they would do if they received a $100 bill by mail, addressed to their neighbor, but wrongly delivered to them. Would they return it to their neighbor? Of the 100 males sampled, 87 said yes and of the 130 females sampled, 120 yes. Does the data indicate that the proportions that said yes are different for male and female at a 5% level of significance? Here we set Ho : P1 = P2, H +a: p1 # P2. By the formula Z= - Pi - P ộiĝi + Ô2ĝ2' V ni we find Z= -1.30. Then, the P-value is: Tn2 (A) 0.1936 (B) 0.0968 (C) 0.5906 (D) 0.2119 (E) 0.4308.

Answer 1

solution: Given z = -1.30 p-vale of = -1.30 caluulator & 0.1936 Therefore the correct from the option is a CS Scanned with p

Answer 2

ANSWER :

Since, z = - 1.30 .

So, p-value from the z-score calculator :

(Ref. https://www.socscistatistics.com/pvalues/normaldistribution.aspx)

Enter : z = - 1.30 

Select : significance level = 0.05 

Select : one-tailed 

Press calculate  .

We get p-value = 0.0968 

So,

Option B :  0.0968 is the ANSWER.
