calculate mean of the table

The table shows the number of fruits sold at a fruit store on seven consecutive days. Using the table, calculate the mean number of fruits sold per day. Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 Fruits sold 9 12 15 18 24 6 21 => 14 or 16 or 15 or 13..

In order to find the mean weight of elephants in a zoo, the weights of all the elephants were measured and the mean calculated. State which of the statements is true. => The group of elephants chosen represents the population for this study. or The group of elephants c..

Calculation of Average Rate of Reaction - Example 2: The gaseous phase decomposition of dinitrogen pentoxide (N 2 O 5 ) to nitrogen dioxide (NO 2 ) and oxygen (O 2 ) is given by, For the reaction the concentration of O 2 was monitored and the following data were obtained. Time/s 0 600 120..

Calculation of Cell Potential - In an electrochemical cell, electrons flow from negative electrode to the positive electrode. This shows that there is a potential difference between the two electrodes. The minimum potential which causes the flow of the electrons from the negative electrod..

The mean of 50 observations was calculated as 38. It was discovered later, that two observations 73 and 37 were misread as 13 and 87 respectively. The correct mean is ________ => 38.9 or 38 or 38.6 or 38.2 or 38.4..

In the discrete series, when deviations are taken from actual mean, the formula is: ..

Merits: 1. Mean deviation is easy to calculate. This measure is simple to understand. 2. This can be calculated from any average. 3. It is less affected by extreme observations. Demerits: 1. This is mathematically incomplete beca..

For a sample mean of 35.3, and a given standard deviation the 95% confidence interval for a population mean was calculated as 33.894 < μ < 36.316. Which is the correct representation after rounding the values? => 33.894 < μ < 36.316 or 33.89 < μ..

The tangent and cotangent came via a different route from the chord approach of the sine. These developed together and were not at first associated with angles. They became important for calculating heights from the length of the shadow that the object cast. The length of shadows wa..

In 1869, Mendeleev classified the then known 56 elements on the basis of their physical and chemical properties by giving a law known as the periodic law. The name periodic law stems from the fact that the properties of the elements orderly recur in a cyclic fashion. His periodic law states that "t..
