A limnologist wishes to estimate the mean phosphate content per unit volume of lake water. It is knownfrom studies in previous y

telo118 [61]

Answer: 68

Step-by-step explanation:

As per given , we have

Population standard deviation : $\sigma=4$

Critical value for 90% confidence interval = $z_{\alpha/2}=1.645$

Margin of error : E= 0.8 milligrams

The formula to find the sample size is given by :-

$n=(\dfrac{z_{\alpha/2}\ \sigma}{E})^2$

i.e. $n=(\dfrac{(1.645)(4)}{0.8})^2=(8.225)^2$

$=67.650625\approx68$

Hence, the limnologist must analyze 68 samples.

Mekhanik [1.2K]

Answer:

<h2>15 passengers </h2>

Step-by-step explanation:

Original price,

Fare for 12 passengers = Rs 540

Fare for 1 passenger = $\frac{540}{12} = 45$

Increased price,

Fare for 1 passenger = 45 + 5 = Rs 50

Let fare for X passengers be 750

$x \times 50 = 750$

$x = \frac{750}{50}$

$x = 15$

Hence, 15 passengers can travel for Rs 750.

Hope this helps...

Good luck on your assignment..
