The solution to the inequality in interval form is (-∞, -1/4)
<h3>Inequality expressions</h3>
Inequality are expressions not separates by an equal sign. Given the inequality below;
x+1<3/4
Subtract 1 from both sides to have;
x + 1 - 1 < 3/4 - 1
x < 3/4 - 1
x < (3-4)/4
x < -1/4
Hence the solution to the inequality in interval form is (-∞, -1/4)

Answer: We should reject the null if the test statistic is greater than <u>1.895</u>. 
Step-by-step explanation:
We assume the population to be normally distributed.
Given:  Sample size :  , which is asmall sample (n<30), so we use t-test.
, which is asmall sample (n<30), so we use t-test.
We always reject the null hypothesis if the absolute t-value is greater than critical value. 
Therefore, We should reject the null if the test statistic is greater than <u>1.895</u>.
