Ch11 case Golf 1. is mean driving distances of current balls is mean driving distances of new balls is mean driving distances of sampled current balls is mean driving distances of sampled new balls Use the test statistics and normal distribution table to get p-value. If p-value is smaller than‚ then we reject H0‚ which means the mean driving distances of current balls and new balls are different. 2. From the t distribution table we find that p-value is between 0.05 and 0

Methodology of estimating the population in UAE 1) The Component Method : This method is used when data are available from a census (base year population) ‚ administrative records of births and deaths and net migration. The estimate is obtained by adding both natural increase and net migration that have occurred since the last census according to following formula: Pt = Po+B-D+I-E Where: Pt The Current Estimate Po The Base Year resident Population (2005 census).

Q1 In a test given to 500 students‚ the average marks was 56 and the standard deviation was 20. Find (i) the number of students exceeding a score of 60. (ii) the number of students having marks between 50 and 70. (iii) the value of marks exceeded by the top 100 students. Answer-------- (i) number of students exceeding a score of 60=210 (ii) The number of students having marks between 50 and 70=188 (iii) The value of marks exceeded by the top 100 students=73 Q2. Following

Statistics Essay Mean is the arithmetic average of a distribution‚ obtained by adding the scores and then dividing it by the number of scores there are. Median is the middle score in a distribution; half the scores are above it and half the scores are below it. Mode is the most frequently occurring score in a distribution. A skewed distribution is when the distribution is leaning toward one side. It is the measure asymmetric probability and its real value of data. A skewed would be like a group

Statistics Paper Driving is a very dangerous and often hazardous thing to do. This is especially true for people ages fifteen to nineteen. There are so many crashes each year for teen drivers that it’s a miracle anyone makes it past twenty years old unharmed. In 2009 alone three hundred and fifty teens were treated for a car related accident. Teen car crashes are preventable. Often times teens drink before they drive or while they drive which makes the vehicle
