<em>To maximize their profit, Esibu must build 6 (2 grandmother clock and 4 wall clock) while Dela must build 8 (6 grandmother clock and 2 wall clock).</em>

Step-by-step explanation:

Since they don't want to work for more than 20 hrs in a week

In-order to maximize the profit,

For Esibu,

2 grandmother clock = 4 hours ×2 = 8 hours

4 wall clock = 3 hours × 4 = 12 hours

Total hours = 20 hours.

For Dela,

6 grandmother clock = 2 hours × 6 = 12 hours

2 wall clock = 4 hours × 2 = 8 hours

Total hours = 20 hours.

A random sample of 100 U.S. adults were selected from a population. In the population, the probability of having hypertension is

svp [43]

Answer:

For this case we want to calculate this probability:

$P(X\leq 30)$

And for this case if we use the normal approximation we can use the z score formula given by:

$z = \frac{X -\mu}{\sigma}$

And using this formula with the correction factor of continuity we got:

$P(X\leq 30) =P(X$

And using the normal standard table or excel we got:

$P(Z \leq 1.522)= 0.936$

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest "number of people with hypertension", on this case we now that:

$X \sim Binom(n=100, p=0.24)$
