Functionally important traits in animals tend to vary little from one individual to the next within populations, possibly becaus

Jet001 [13]

Answer:

The 95% confidence interval for the standard deviation is (0.14, 0.54).

Step-by-step explanation:

The complete data and question is:

Sloth CW Ratios ; {1.5 , 1.09 , 0.98 , 1.42 , 1.49 , 1.25}

The 95% confidence interval for the standard deviation of this data is < σ < (two decimals - include the leading zero) .

Solution:

Compute the sample standard deviation as follows:

$\bar x=\frac{1}{n}\sum x=\frac{1}{6}\times 7.73=1.2883\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{6-1}\times 0.2387}=0.2185$

The (1 - <em>α</em>)% confidence interval for the variance is:

$CI=\frac{(n-1)s^{2}}{\chi^{2}_{\alpha/2}}$

Confidence level = 95%

⇒ α = 0.05

The degrees of freedom is,

df = n - 1 = 6 - 1 = 5

Compute the critical values of Chi-square:

$\chi^{2}_{\alpha/2, (n-1)}=\chi^{2}_{0.025,5}=12.833\\\\\chi^{2}_{1-\alpha/2, (n-1)}=\chi^{2}_{0.975,5}=0.831$

*Use a Chi-square table.

Compute the 95% confidence interval for the variance as follows:

$CI=\frac{(n-1)s^{2}}{\chi^{2}_{\alpha/2}}$

$=\frac{5\times (0.2185)^{2}}{12.833}$

Thus, the 95% confidence interval for the standard deviation is (0.14, 0.54).

Given the rule Xn = 10 * 3(n-1), find the<br> 11th term of the sequence

Elan Coil [88]

Answer:

X11 = 300

Step-by-step explanation:

X11 = 10 × 3(11 - 1)

X11 = 10 × 3(10)

X11 = 10 × 30

X11 = 300
