A paired difference experiment yielded na pairs of observations. In each case, what is the rejection region for testing H,: Hd =2 against Ha: Hd> 2? a. na = 11, a = 0.05 t > 1.812 (Round to three decimal places as needed.) b. ng = 22, a = 0.10 (Round to three decimal places as needed.)
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

A paired difference experiment yielded \( n_d \) pairs of observations. In each case, what is the rejection region for testing \( H_0: \mu_d = 2 \) against \( H_a: \mu_d > 2 \)?
a. \( n_d = 11, \alpha = 0.05 \)
\[ t \geq 1.812 \; \text{(Round to three decimal places as needed.)} \]
b. \( n_d = 22, \alpha = 0.10 \)
\[ t \geq \; \text{(Round to three decimal places as needed.)} \]
Please note: This text involves a statistical hypothesis test utilizing a t-distribution critical value table to determine the rejection region based on the given significance level (α) and degrees of freedom (from \( n_d \)). The rejection region is specified by the critical t-value needed to reject the null hypothesis \( H_0 \) in favor of the alternative hypothesis \( H_a \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0dffadf4-6195-4ecd-8325-0f00263ddf75%2F193076db-8be0-4421-8a0b-39fd6cb50e8c%2Fctt3xxj_processed.jpeg&w=3840&q=75)
