Answer 1

Step-by-step explanation:

1.7142

1.7142To find mean we will add up total number or children, then divide by number of families.

1.7142To find mean we will add up total number or children, then divide by number of families.So,

1.7142To find mean we will add up total number or children, then divide by number of families.So,Mean =

1.7142To find mean we will add up total number or children, then divide by number of families.So,Mean = (11+25+32+10+5+1)

1.7142To find mean we will add up total number or children, then divide by number of families.So,Mean = (11+25+32+10+5+1)(0×11+1×25+2×32+3×10+4×5+5×1)

1.7142To find mean we will add up total number or children, then divide by number of families.So,Mean = (11+25+32+10+5+1)(0×11+1×25+2×32+3×10+4×5+5×1)

1.7142To find mean we will add up total number or children, then divide by number of families.So,Mean = (11+25+32+10+5+1)(0×11+1×25+2×32+3×10+4×5+5×1)

1.7142To find mean we will add up total number or children, then divide by number of families.So,Mean = (11+25+32+10+5+1)(0×11+1×25+2×32+3×10+4×5+5×1) Mean =(25+64+30+20+5)/84

1.7142To find mean we will add up total number or children, then divide by number of families.So,Mean = (11+25+32+10+5+1)(0×11+1×25+2×32+3×10+4×5+5×1) Mean =(25+64+30+20+5)/84=144/84=1.7142

1.7142To find mean we will add up total number or children, then divide by number of families.So,Mean = (11+25+32+10+5+1)(0×11+1×25+2×32+3×10+4×5+5×1) Mean =(25+64+30+20+5)/84=144/84=1.7142Therefore,the mean number of children per family is 1.7142

Answer 2

Answer:

2

Step-by-step explanation:

number of families= 0 1 2 3 4 5

no of children = 0 1 2 3 4 5

mean = no of families/ no of children*2

0+1+2+3+4+5÷0+1+2+3+4+5*2

=2.
