<u>Check One-Sample T-Interval Conditions</u>
Random Sample? √
Sample Size ≥30? √
Independent? √
Population Standard Deviation Unknown? √
<u>One-Sample T-Interval Information</u>
- Formula -->

- Sample Mean -->

- Critical Value -->
(given
degrees of freedom at a 95% confidence level) - Sample Size -->

- Sample Standard Deviation -->

<u>Problem 1</u>
The critical t-value, as mentioned previously, would be
, making the 95% confidence interval equal to 
This interval suggests that we are 95% confident that the true mean levels of lead in soil are between 381.5819 and 398.9181 parts per million (ppm), which satisfies the EPA's regulated maximum of 400 ppm.
Answer:
The correct answer is 0.004382 kW/K, the second law is a=satisfied and established because it is a positive value.
Explanation:
Solution
From the question given we recall that,
The transferred heat rate is = 2kW
A reservoir cold at = 300K
The next step is to find the rate at which the entropy of the two reservoirs changes is kW/K
Given that:
Δs = Q/T This is the entropy formula,
Thus
Δs₁ = 2/ 300 = 0.006667 kW/K
Δs₂ = 2 / 875 =0.002285
Therefore,
Δs = 0.006667 - 0.002285
= 0.004382 kW/K
Yes, the second law is satisfied, because it is seen as positive.
Answer:
Quantity.
Explanation:
A standardized prescription is one that contains generic prescriptions indicated for a certain disease, that is, one that contains the basic treatments indicated for it, including drugs and treatments prescribed in uniform quantities and qualities for all patients. Thus, these recipes do not aim at the individual characteristics of the patient, but at the general characteristics of the diagnosed disease and its main treatments.
