Answer:

(A)

Step-by-step explanation:

For type 1, the given data set is:

{42, 56, 44, 60, 48}

Mean of the given data is:

Mean=\frac{42+56+44+60+48}{5}=50

Data set                                                       (x-{\overline{x}})^2

42                                                                     64

56                                                                     36

44                                                                      36

60                                                                     100

48                                                                       4

Now, Variance=\frac{64+36+36+100+4}{5}=48

Thus, standard deviation=\sqrt{Variance}=\sqrt{48}=6.92

The difference in the standard deviation and mean of type 1 data set is =50-6.92=43.08.

For type 2:

{62, 59, 68, 55, 66}

Mean of the given data is:

Mean=\frac{62+59+68+55+66}{5}=62

Data set                                                       (x-{\overline{x}})^2

62                                                                     0

59                                                                     9

68                                                                    36

55                                                                    49

66                                                                     16

Now, Variance=\frac{0+9+36+49+16}{5}=22

Thus, standard deviation=\sqrt{Variance}=\sqrt{22}=4.69

The difference in the standard deviation and mean of type 1 data set is =62-4.69=57.31.

Since, difference in the standard deviation and mean of both type 1 and type 2 are different, therefore Type 1 plants and Type 2 plants do not have similar height distributions.
