Apoll showed that 48 out of 120 randomly chosen graduates of california medical schools last year intended to specialize in family practice. what is the width of a 90 percent confidence interval for the proportion that plan to specialize in family practice? select one: a. ± .0736b. ± .0447c. ± .0876d. ± .0894

± 0.0736

Step-by-step explanation:

Data provided in the question:

randomly chosen graduates of California medical schools last year intended to specialize in family practice, p = = 0.4

Confidence level = 90%

sample size, n = 120

Now,

For 90% confidence level , z-value = 1.645

Width of the confidence interval = ± Margin of error

= ±

= ±

= ± 0.07356 ≈ ± 0.0736

Hence,

The correct answer is option  ± 0.0736

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
