<em>It may seem that the options have been omitted in this question. However, in order to evaluate the claim that a mean from a particular group is statistically higher or lower to a mean from another group, there would be a need to compare the two means. </em>
Mean comparison or testing for a significant difference between means can be carried out using the Student's t-test or one-way Analysis of Variance (ANOVA).
When the means being compared are just for 2 groups as indicated in the illustration, Student's t-test and one-way ANOVA can be used. However, once there are more than 2 group means being compared, one-way ANOVA will only be applicable.
Answer: By losing its two outermost electron
Explanation:
Calcium is a element that belongs to group 2 in the periodic table. It has an atomic number of 20, and an electronic configuration of 2, 8, 8, 2.
Hence, to form an octet structure, it gives off its two electrons as shown below:
Ca <----> Ca2+ + 2e-
Thus, by losing its two outermost electrons, a positively charged calcium ion (Ca2+) is formed
