assume that random guesses are made for 8 multiple choice questions on an SAT test, so that there are n=9 trials, each with prob

melamori03 [73]

Answer:

$P(x$

Step-by-step explanation:

If we call x the number of correct questions obtained in the 9 attempts, then:

x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.

So, the p of x successes has the following formula.

$P(x) =\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}$

Where:

n = 9

p = 0.6

We are looking for P(x<4)

By definition:

$P(x$

Then:

$P(x\leq3)=\sum_{x=0}^{3} \frac{9!}{x!(9-x)!}*(0.6)^x(1-0.6)^{9-x}$

$P(x\leq3)=0.0994$

A survey of 2380 golfers showed that 366 of them are left-handed. Find a point estimate for p, the population proportion of golf

cluponka [151]

Answer:

The point estimate is 366/2380

Step-by-step explanation:

Here. we want to find a point estimate for the number of golfers that are left-handed

To get this, we simply divide the number of left-handed golfers by the number of golfers surveyed

Mathematically, this will be 366/2380
