A veterinarian investigating possible causes of enteroliths in horses suspects that feeding alfalfa may be to blame. She wishes

Ghella [55]

Answer: b. (0.561, 0.794).

Step-by-step explanation:

We know that the confidence interval for population proportion (p) is given by:-

$\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

, where $\hat{p}$ = Sample proportion.

n = Sample size.

z* = Critical z-value.

Let p = proportion of horses with enteroliths who are fed at least two flakes of alfalfa per day.

As per given , n = 62

$\hat{p}=\dfrac{42}{62}=0.67742$

z-value for 95% confidence = z*=1.96

A 95% confidence interval is given by:

$0.67742\pm (1.96)\sqrt{\dfrac{0.67742(1-0.67742)}{62}}\\\\ =0.67742\pm 0.11636\\\\ =(0.67742-0.11636,0.67742+0.11636 )\\\\=(0.56106, 0.79378)\approx(0.561,0.794 )$

Thus , the required 95% confidence interval is (0.561, 0.794).

Hence, the correct option is b. (0.561, 0.794)..

Valuate the xpression 4(10-4) power of 2 devided by 4

liq [111]

Hence, the value of the expression is 36.

Solution:

Step 1: Given expression is $4(10-4)^{2} \div 4$ .

BODMAS means do Bracket, Of, Division, Multiplication, Addition, Subtraction

Step 2: Using BODMAS rule first simplify the expression which is in bracket.

⇒ $4(10-4)^{2} \div 4=4(6)^2\div4$

Step 3: Squaring of the number 6.

⇒ $4(6)^2\div4=4\times36\div4$

Step 4: Using BODMAS rule, divide 36 by 4.

⇒ $4\times36\div4=4\times9$

Step 5: Using BODMAS rule, multiply 4 with 9.

⇒ $4\times9=36$

Hence, the value of the expression is 36.

Answer:

down below

Step-by-step explanation:

The line slopes downwards as we move from left to right. The vertical intercept is 5. The gradient measures the steepness of the line. A large positive value of m means the graph increases steeply as you move from the left to the right. Answer.
