Answer:

7

Step-by-step explanation: ( ^ means squared)

distance formula

Square root of(y1-y2)^ + (x2 - x1)^  Square root of everything

Square root of (4-4)^ + 4- (-3)

= square root of 0 + 7^

=square root of 7^ = 7

You plan to conduct a marketing experiment in which students are to taste one of two different brands of soft drink. Their task
Talja [164]

Answer:

the probability is 90% that the sample percentage is contained within 45.5% and 54.5% symmetric limits of the population percentage.

Step-by-step explanation:

From the given information:

Sample size n = 200

The standard deviation for a sampling distribution for two brands are equally likely because the individual has no ability to discriminate between the two soft drinks.

∴

The population proportion p_o = 1/2 = 0.5

NOW;

\sigma _p = \sqrt{\dfrac{p_o(1-p_o)}{n}}

\sigma _p = \sqrt{\dfrac{0.5(1-0.5)}{200}}

\sigma _p = \sqrt{\dfrac{0.5(0.5)}{200}}

\sigma _p = \sqrt{\dfrac{0.25}{200}}

\sigma _p = \sqrt{0.00125}

\sigma _p = 0.035355

However, in order to determine the symmetrical limits of the population percentage given that the z probability is 90%.

we use the Excel function as computed as follows in order to determine the z probability  = NORMSINV (0.9)

z value = 1.281552

Now the symmetrical limits of the population percentage can be determined as: ( 1.28, -1.28)

1.28 = \dfrac{X - 0.5}{0.035355}

1.28 × 0.035355 = X - 0.5

0.0452544= X - 0.5

0.0452544 + 0.5 = X

0.5452544 = X

X \approx 0.545

X = 54.5%

-1.28 = \dfrac{X - 0.5}{0.035355}

- 1.28 × 0.035355 = X - 0.5

- 0.0452544= X - 0.5

- 0.0452544 + 0.5 = X

0.4547456 = X

X \approx 0.455

X = 45.5%

Therefore , we can conclude that the probability is 90% that the sample percentage is contained within 45.5% and 54.5% symmetric limits of the population percentage.
