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 $\=x_1=3.18$

Standard deviation $\delta_! =1.72$

Sample size $n_1 =51$

Sample mean $\=x_2=2.22$

Standard deviation $\delta_2 =0.67$

Sample size $n_2=20$

Generally this is a two tailed test

therefore

Null hypothesis = $h_0 :P_v_e_g= P_n_o_n_v_e_g$

Alternative hypothesis $H_a : P_v_e_g \neq P_n_o_n_v_e_g$

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
