The value that distinguishes the lowest 25% of data from the highest 75% is -0.00235. Previous concepts: Normal distribution, which describes a "probability distribution that is balanced around the mean, indicating that data close to the mean occur more frequently than those further away from it". The Z-score is "a statistical measurement relating a value to the mean of a set of values, in terms of its distance in standard deviations from the mean". To solve the problem, let X represent the variable of interest in a population; we know the distribution for X is given by:... We want to find a value a to satisfy the condition:... Both conditions here are equivalent. We can apply the Z-score again to find the value a. The figure shows that the z value meeting the condition with 0.25 of the area to the left and 0.75 to the right is z = -0.674. Therefore, P(Z < -0.674) = 0.25 and P(z > -0.674) = 0.75. We can use condition (b) previously to derive... We know the z value that satisfies the equation, so we can proceed to solve for a, which gives us... Thus, the value that separates the lower 25% of data from the upper 75% is -0.00235.
Answer:
The variable cost per unit sold amounts to $11.50
Explanation:
The computation for the variable cost per unit sold is provided below:
= Direct materials per unit + Direct labor per unit + Variable manufacturing overhead per unit + Sales commissions per unit + Variable administrative expenses per unit
= $4.85 + $3.35 + $1.35 + $1.50 + $0.45
= $11.50
Simply put, we summed up the respective per unit costs attributable to variable expenses per unit
After evaluating the email, it's clear that it lacks formal tone and is missing a proper subject line. The email opens rather bluntly and unprofessionally. It also includes negative expressions, such as "unfortunately I cannot buy extra license." Here’s a revised version:

Subject: Informing about the Adobe Creative Cloud access request.
Dear staff,
This email serves to notify you that we cannot procure additional access to the Adobe Creative Cloud for personal use due to high costs and the expensive nature of access codes. I extend my apologies to those who sought this privilege.
The cloud suite offers numerous features, and I would be happy to demonstrate it if you contact the Document Production Department. Keep in mind that this software operates on a subscription basis and requires unique access keys, which cannot be used on more than one computer. I appreciate your understanding regarding this matter, and if additional access were granted, it might not be beneficial for our business.
Thank you for your cooperation.
Best regards,
Anna He Wong
Document Production Manager.
