Answer:

d. Approximate the standard normal distribution with the Student's t distribution

(0.2199 ; 0.2327)

Step-by-step explanation:

Given that :

Sample size, n = 31

Sample mean, xbar = 0.2258

Sample standard deviation, s = 0.0188

Confidence interval (C. I) :

xbar ± margin of error

Margin of Error : Tcritical * s/sqrt(n)

Degree of freedom, df = n - 1 = 31 - 1 = 30

Tcritical value :

T0.05/2, 30 = 2.042

Margin of Error = 2.042 * 0.0188/sqrt(31)

Margin of Error = 0.0068949

C. I = 0.2258 ± 0.0068949

Lower boundary : (0.2258 - 0.006895) = 0.2189

Upper boundary : (0.2258 - 0.006895) = 0.2327

(0.2199 ; 0.2327)

Help can u answer this

Answer:

$c) 82$

$d) - 11$

$g)27$

$h)1000$

$k)11$

$l) 8$

Step-by-step explanation:

${9}^{2} + 1 \\ = (9 \times 9) + 1 \\ = 81 + 1 \\ = 82$

${6}^{2} - {5}^{2} \\ = (6 \times 6) - (5 \times 5) \\ = 36 - 25 \\ = - 11$

$(1 + 2 {)}^{3} \\ = {3}^{3} \\ = 3 \times 3 \times 3\\ = 27$

$(2 + 8 {)}^{3} \\ = {10}^{3} \\ = (10 \times 10 \times 10) \\ = 1000$

$\sqrt{4} + {3}^{2} \\ = 2 + {3}^{2} \\ = 2 + (3 \times 3) \\ = 2 + 9 \\ = 11$

$2 \times 5 - \sqrt{4} \\ = 10 - \sqrt{4} \\ = 10 - 2 \\ = 8$
