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.
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>.

<h3>What is index form?</h3>
Index form is defined as the power or exponent which is raised to a number or a variable.
For example, in number 5^2, 2 is the index of 5.
Indices is the plural form of index.
To add index forms, we need to note the following:
- Both the exponents and variables should be same
- Add the coefficients of the variables leaving the exponents unchanged.
- Only terms that have same variables and powers are added
Given:
(3.012 x 10−8) + (4 x 10−8)
3. 012 + 4 (10^-8)
7. 012 × 10^-8
Thus, the sum is 7. 012 × 10^-8. Option C

M = -2/3, B(2, -5), x₁ = 2, y₁ = -5
y - y₁ = m(x - <span>x₁)
</span>y - -5 = -(2/3)(x - 2<span>)
</span>
3(y + 5) = -2(x - 2)
3y + 15 = -2x + 4
3y + 2x = 4 - 15
3y + 2x = -11
