প্রশ্নে বলা হচ্ছে, জরিপের 3 জন সর্বোচ্চ স্কোরধারীর সর্বোচ্চ গড় Study এর সময় কত?

এখানে 165 স্কোরধারী দুইজনের Study hour হলো যথাক্রমে 28 এবং 45 ঘণ্টা 

আর তৃতীয় জনের স্কোর হলো 155 যার Study hour হলো 43.

$\therefore$তাদের গড় Study hour হলো = $\frac{28+43+45}{3}=38.5$ ঘণ্টা

প্রশ্নে বলা হচ্ছে, এই জরিপের ছাত্রদের মধ্যে যারা 20 ঘণ্টা বা তার চেয়ে বেশি সময় Study করেছে, মডেল অনুযায়ী তাদের কতজন প্রত্যাশার চেয়ে খারাপ করেছে? 

প্রত্যাশার চেয়ে যারা খারাপ করেছে তাদের অনুপাত বের করার জন্য আমরা 20 ঘণ্টা Study এর হর এবং লব নিয়ে নিচেন মতো করে করি । এখানে Gray dot গুলি বাদ যাবে যেহেতু তাদের মান 20 ঘণ্টার কম । বাকি Dot গুলোর মধ্যে 7 টি সরু Dot উপরে এবং 3টি লাল Dot নিচে। এই (3 + 7 ) = 10টি Dot 20 ঘণ্টা লাইনের উপরে থাকে।

$\therefore$নির্ণের ভগ্নাংশ $\frac{3}{10}$

Many people believe that women make better parents than men and that is why they have the greater role in raising children in most societies. Others claim that men are just as good as women at parenting. 

We begin our lives with our mothers and our fathers. We grow up under protection of our parents. They supply what we need. They are responsible to our health until we grow up. Some people say that mothers are better parents but I believe that we need both of them. Our fathers work hard to earn money and buy the things that we need. They are financial supporter of our families. They buy food for us. The also supply a home where we need to stay and grow up. They also pay money for every thing that we need to buy or pay money for it. When we want to go to university we need money, Our fathers pay this money for us. 

To do all these responsibilities properly they must have money and so they should work hard. So some times they do not have enough time to be with us and we may think that they don't notice to us. I believe that our fathers like our mothers think about us and they try to make better lives for us. I lost my father about 7 years ago and I didn't have this chance to have his protection after his death. I accept that mothers are very kind. They role in raising children is inevitable but we can not deny our fathers role. After that event my mother tried more than before and she was a mother and also a father for me. 

To sum up I believe that children need to their father like their mother and the role of both of them is important in children lives.
