The distribution of number of hours worked by volunteers last year at a large hospital is approximately normal with mean 80 and
Mazyrski [523]

Explanation:

Using the normal distribution, it is found that the probability that the volunteer selected will receive a certificate of merit given that the  number of hours the volunteer worked is less than 90 is closest to:

B 0.123

In a normal distribution with mean \muμ and standard deviation \sigmaσ , the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}Z=σX−μ

It measures how many standard deviations the measure is from the mean.  

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

The mean is of 80, hence \mu = 80μ=80 .

The standard deviation is of 7, hence \sigma = 7σ=7 .

The minimum value is the 80th percentile, which means that it is X_mXm when Z has a p-value of 0.8.

The probability that the volunteer selected will receive a certificate of merit given that the number of hours the volunteer worked is less than 90 is P(X_m < X < 90)P(Xm<X<90) , which is the p-value of Z when X = 90 subtracted by the p-value of Z when X = X_mX=Xm , hence the p-value of Z when X = 90 subtracted by 0.8.

Z = \frac{X - \mu}{\sigma}Z=σX−μ

Z = \frac{90 - 80}{7}Z=790−80

Z = 1.43Z=1.43

Z = 1.43Z=1.43 has a p-value of 0.9236.

0.9236 - 0.8 = 0.1236, hence closest to 0.123, option B.

Assume that thermometer readings are normally distributed with a mean of 100o F and a standard deviation of 0.15o F. a) Draw and
son4ous [18]

The parameters of the normal distribution of the thermometer readings are its mean and the standard deviation

The probability that a thermometer reading is between 99.86o F and 100.07o F is 0.5403

<h3>The sketch of the normal distribution of the thermometer</h3>

The given parameters are:

  • Mean, μ = 100
  • Standard deviation, σ = 0.15

Next, we draw the normal distribution using a graphing calculator.

See attachment for the sketch of the normal distribution of the thermometer

<h3>The probability that a thermometer reading is between 99.86o F and 100.07o F</h3>

This means that:

x = 99.86 and x = 100.07

The probability is calculated as:

P(99.86 < x < 100.07) = P(x > 99.86) - P(x < 100.07)

Using the attached graph, we have:

P(99.86 < x < 100.07) = 0.5403

How did John Watson contribute to Psychology??
Klio2033 [76]
John Watson believed that psychology should primarily be scientific observable behavior. He is remembered for his research on the conditioning process. Watson is also known for the Little Albert experiment, in which he demonstrated that a child could be conditioned to fear a previously neutral stimulus.
