Answer:
Step-by-step explanation:
In hypothesis testing if p value < alpha i.e. our significance level we reject null hypothesis
Consider for example, 95% confidence level is taken, and p value one tailed is 0.026. Since p <0.05, We reject null hypothesis
p value two tailed is twice p value for one tailed. Hence p value two tailed =0.052.
Since p value >0.05 our alpha. So in this case, null hypothesis will be accepted
Hence sometimes it would be rejected and sometimes it would be accepted
Using either the critical value rule or the p-value rule, if a one-sided null hypothesis is rejected at a given significance level, then the corresponding two-sided null hypothesis (i.e., the same sample size, the same standard deviation, and the same mean) need not ______________ be rejected at the same significance level.

Step-by-step explanation:
( secA + 1)( sec A - 1)
Using the expansion
( a + b)( a - b) = a² - b²
Expand the expression
We have
sec²A + secA - secA - 1
That's
sec² A - 1
From trigonometric identities
<h3>sec²A - 1 = tan ²A</h3>
So we have the final answer as
<h3>tan²A</h3>
As proven
Hope this helps you
