Express the confidence interval 0.319 < p < 0.488 in the form of p ± E.
KengaRu [80]

Answer:

0.4035+/-0.0845

Step-by-step explanation:

The fundamental step would be to determine the values of p and E which i believe is the margin of error in this case. Consider the following two equations;

p-E=0.319\\p+E=0.488

We simply add the two equations and solve for p;

2p=0.807\\p=0.4035

We then substitute this value of p in either equation and solve for E;

0.4035-E=0.319\\E=0.0845

Since we have both p and E, the confidence interval can thus be written as;

0.4035+/-0.0845

A bowl has 3 red beads and 7 blue beads. Two beads are selected at random one at a time. First a red bead is drawn and placed on
IceJOKER [234]

The probability that first a red bead is drawn and next a blue bead is drawn is 7/30,and both events are dependent

<h3>How to determine the probability?</h3>

The distribution of the beads are:

Red = 3

Blue = 7

Total = 10

The probability of selecting the red bead first is:

P(Red) = 3/10

When the red bead is selected, the number of beads becomes 9

So, the probability of selecting a blue bead is

P(Blue) = 7/9

The probability of the event is then calculated using:

P = 3/10 * 7/9

Evaluate

P = 7/30

Hence, the probability of the event is 7/30
