Answer:
p² +3p -10
Step-by-step explanation:
The distributive property applies.
= p(p -2) +5(p -2) . . . . . . distribute factor (p-2) to both terms in the first parentheses
= p² -2p +5p -10 . . . . . . distribute p and 5 to the terms in parentheses
= p² +3p -10 . . . . . . . . . . combine p terms

Answer:
There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance.
Step-by-step explanation:
When our p-value exceeds level of significance then we fail to reject our null hypothesis. In this scenario we are investigating if there exists significant difference in the birth weights of a mother's first child and second child and our null hypothesis is there exists no significant difference in the birth weights of a mother's first child and second child i.e.μd=0.
As we are given that p-value is greater than 10% level of significant so, we cannot reject our null hypothesis. Thus, the conclusion statement can be written as "There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance."
The opposite of -3.4 would be positive 3.4
