The 95% confidence interval is  (29.54 - 53.46}

Step-by-step explanation:

given data:

\hat X = 41.5

Se = 6.1

n = 755

a) best estimate  \hat x = 41.5

b) at 95% confidence interval

\alpha = 1- 0.95 = 0.05

\alpha /2 = 0.025

z_{\alpha/2} = z_{0.025} = 1.96

at 95% confidence interval for [/tex]\mu[/tex]

\hat x \pm z_{\alpha /2} \times Se

41.5 \pm 1.96\times 6.1

41.5 \pm 11.96

The 95% confidence interval is  (29.54 - 53.46}

Evaluate the following.<br> (iii) sin 30° + tan 40° - cosec 60° / cot 45° + cos 60° - sec 30°​
bearhunter [10]

Sin 30 = 1/2

tan 45 = 1

Cosec 60 = 2 / √3 = 2√3 / 3

cot 45 = 1

Cos 60 = 1/2

sec 30 = 2 / √3 = 2√3 / 3

_______________________________

[ 1/2 + 1 - 2√3/3 ] ÷ [ 1 + 1/2 - 2√3/3 ] = <em>1</em>

The face and denominator of the fraction are exactly the same thus the answer is 1 .
