Answer:

The answer to your question is: Oxygen (O) and Selenium (Se)

Explanation:

Elements located in group VIA needs to gain 2 electrons to achieve noble gas electron configuration.

Oxygen (O) is located in group VIA so it needs to gain two electrons to become stable.

Strontium (Sr) is located in group IIA so it needs to lose 2 electrons to become stable.

Sodium (Na) is located in group IA so it needs to lose one electron to become stable.

Selenium (Se) is located in group VIA so it needs to gain 2 electrons to become stable.

Bromine (Br) is located in group VIIA so it needs to gain one electron to become stable.

The p-value of a statistical test depends on all of the following, except:
vaieri [72.5K]

Answer:

The correct option is e.

Explanation:

p-value is the probability value for a given statistical model, the probability that, when the null hypothesis is true.

For two two samples the formula of test statistics is

t=\frac{(\overline{x}_1-\overline{x}_2)-(\mu_1-\mu_2)}{\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}}

where,

\overline{x} is sample mean

\mu is population mean.

s is standard deviation.

n is sample size.

Variance is the square of standard deviation.

It means variance, mean, numbers of samples is used in calculation of p-value.

Degree of freedom define the shape of the t-distribution that your t-test uses to calculate the p-value.

d.f.=n_1+n_2-2

p-value of a statistical test depends on all of the following, except median.

Therefore the correct option is e.
