Answer:
There isn't one.
Step-by-step explanation:
The square root of a negative number is imaginary. There is no real number that is the square root of -3.24.
Answer:
From the test give in the question it is obvious that there is enough evidence to show that population mean varies for vegetarian and non-vegetarian
The P-value helps affirm the null hypothesis claims,The P-value attains values relatively as large as that which exists in the sample given,if the null hypothesis is right
Step-by-step explanation:
From the question we are told that
Sample mean ![\=x_1=3.18](https://tex.z-dn.net/?f=%5C%3Dx_1%3D3.18)
Standard deviation ![\delta_! =1.72](https://tex.z-dn.net/?f=%5Cdelta_%21%20%3D1.72)
Sample size ![n_1 =51](https://tex.z-dn.net/?f=n_1%20%3D51)
Sample mean ![\=x_2=2.22](https://tex.z-dn.net/?f=%5C%3Dx_2%3D2.22)
Standard deviation ![\delta_2 =0.67](https://tex.z-dn.net/?f=%5Cdelta_2%20%3D0.67)
Sample size ![n_2=20](https://tex.z-dn.net/?f=n_2%3D20)
Generally this is a two tailed test
therefore
Null hypothesis = ![h_0 :P_v_e_g= P_n_o_n_v_e_g](https://tex.z-dn.net/?f=h_0%20%3AP_v_e_g%3D%20P_n_o_n_v_e_g)
Alternative hypothesis ![H_a : P_v_e_g \neq P_n_o_n_v_e_g](https://tex.z-dn.net/?f=H_a%20%3A%20P_v_e_g%20%5Cneq%20%20P_n_o_n_v_e_g)
From the test give in the question it is obvious that there is enough evidence to show that population mean varies for vegetarian and non-vegetarian
The P-value helps affirm the null hypothesis claims,The P-value attains values relatively as large as that which exists in the sample given,if the null hypothesis is right
