Answer:

the confidence interval for the true weight of the specimen is;

4.1593 ≤ μ ≤ 4.1611

Step-by-step explanation:

We are given;

Standard deviation; σ = 0.001

Sample size; n = 8

Average weight; x¯ = 4.1602

We are given a 99% confidence interval and the z-value at this interval is 2.576

Formula for confidence interval is;

CI = x¯ ± (zσ/√n)

Plugging in the relevant values, we have;

CI = 4.1602 ± (2.576 × 0.001/√8)

CI = 4.1602 ± 0.000911

CI = (4.1602 - 0.000911), (4.1602 + 0.000911)

CI ≈ (4.1593, 4.1611)

Thus, the confidence interval for the true weight will be expressed as;

4.1593 ≤ μ ≤ 4.1611

Where μ represents the true weight

6) Solve for x. 2/3 (x + 7) = 10 <br><br> A)22 <br><br> B)8 <br><br> C)- 1 /3 <br><br> D)41/ 3
Amiraneli [1.4K]

For this case we must find the value of the variable "x" of the following equation:

\frac {2} {3} (x + 7) = 10

We multiply by 3 on both sides of the equation:

2 (x + 7) = 30

We divide between 2 on both sides of the equation:

(x + 7) = 15\\x + 7 = 15

We subtract 7 on both sides of the equation:

x = 8

Option B
