Pavlova-9 [17]

Answer:

30°

Step-by-step explanation:

\tan (m\angle H) = \frac{IJ}{JH} \\  \\  \implies \: \tan (m\angle H) = \frac{  \sqrt{10}  }{ \sqrt{30} } \\  \\\implies \: \tan (m\angle H) = \frac{{1}  }{ \sqrt{3} }  \\  \\ \implies \: \tan (m\angle H) =  \tan 30 \degree \\  \\  \implies \: m\angle H =  \boxed{30} \degree

a researcher at a major clinic wishes to estimate the proportion of the adult population of the united states that has sleep dep
Anna11 [10]

Answer:

The estimate of a population proportion is approximately 541.

Step-by-step explanation:

We can solve the the problem by using the formula for minimum sample needed for interval estimate of a population proportion which is given by the formula

n = pq ((Z/2) / E)^2

As, p is not defined so we use the standard p and q which is 0.5 and 0.5.

The reason for this is we have to choose form 0.1 to 0.9 both values of p and q, we will find the maximum value of pq occurs when they both are 0.5.

Next, we will find the value of (Z/2) by looking at the Z-table, we will find that at 98% confidence (Z/2) = 2.326. Now we start substituting the values in the above formula

n = (0.5)×(0.5) × (2.326/0.05)^2

n = 541.027

n ≅ 541.
