The length of 40 leaves of a plant are measured correct to one millimetre, and the obtained data is represented in the following table :

(ii) Is there any other graphical representation for the same data ?

The length of 40 leaves of a plant is measured correct to the nearest millimetre and the data obtained is represented in the following table. Find the mean length of the leaves.

The length of 40 leaves of a plant are measured correct to one millimetre, and the obtained data is represented in the following table : (iii) Is it correct to conclude that the maximum number of leaves are 153 mm long ? Why ?

The lengths of 40 leaves of a plant are measured correct to the nearest (millimeter, and the data obtained is represented in the following table Find the median length of the leaves. (Hint: The data needs to be converted to continuous classes for finding the median, since the formula assumes continuous classes. The classes then change to 117.5-126.5,126.5-135.5,...,171.5-180.5.)

An insurance company selected 2000 drivers at random (i.e., without any preference of one driver over another) in a particular city to find a relationship between age and accidents. The data obtained is given in the following table: Find the probabilities of the following events for a driver chosen at random from the city: (i) The driver being in the age group 18-29 years and having exactly 3 accidents in one year. (ii) The driver being in the age group of 30-50 years and having one or more accidents in a year. (iii) Having no accidents in the year.

One end of a string of length l is connected to a particle of mass m and the other to a small peg on a smooth horizontal table. If the particle moves in a circle with speed v the net force on the particle (directed towards the centre) is : (i) T, (ii) T - (mv^2)/(l) , (iii) T + (mv^2)/(l) , (iv) 0 T is the tension in the string. [Choose the correct alternative].

Go through the following statements (i) In geometric growth, following mitotic cell division, only one daughter cell continues to divide while the other differentiates and mature. (ii) The ability of plants to follow different pathways in response to environment or phases of life to form different kinds of structures, is called plasticity. (iii) The mathematical expression for arithmetic growth is Lt = L_0 + rt while for geometric growth, it is W_1=W_0=W_(0)e^(rt) (iv) The form of growth wherein new cells are always being added to the plant body by the activity of the meristem, is called the open form of growth. Which of these are correct .

A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is as follows : You were asked to prepare a frequency distribution table, regarding the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city for 30 days . Using this table, find the probability of the concentration of sulphur dioxide in the interval 0.12-0.16 on any of these days.

Read the following statements regarding Mendelian inheritance and choose the correct option. (i) Medel's experiments had small sample size which gave greater credibility to the data. (ii) A true breeding line shows a stable trait inheritance and expression for several generations. (iii) In a dissimilar pair of factors, one member of the pair dominates over the other. (iv) A recessive parental trait is expressed only in its heterozygous condition. (v) Two alleles of a gene are located on homologous sites on homologous.
