/in /by

In a study to assess the effectiveness of garlic for lowering cholesterol, 50 adults were treated with garlic tablets. Cholesterol levels were measured before and after treatment. The changes in their LDL cholesterol (in mg/dL) have a mean of 8 and a standard deviation of 4. 

(a) Construct a 95% interval estimate of the mean change in LDL cholesterol after the garlic tablet treatment. (Round the lower bound and upper bound of the confidence interval to two decimal places) Include description of how confidence interval was constructed. 

(b) Describe the results of the study in everyday language.

In A Study Of Red Green Color Blindness 700 Men And 2050 Women Are Randomly Sele

/in /by

In a study of red/green color blindness,700 men and 2050 women are randomly selected and tested. Among the men, 60 have red/green color blindness. Among the women, 6 have red/green color blindness. Test the claim that men have a higher rate of red/green color blindness.

I need to know:

  • The test statistic
  • The p-value
  • Is there sufficient evidence to support the claim that men have a higher rate of red/green color blindness than women using the 0.05 significance level?
  • Construct the 95 % confidence interval for the difference between the color blindness rates of men and women.

In A Study Does Seeing Black Faces Of Young Black Boys Facilitate The Identifica

/in /by

In a study ” Does seeing black faces of young black boys facilitate the identification of threatening stimuli?” their hypothesis was 

“We anticipated that, as in the prior experiments, participants would have less difficulty categorizing threat-related words and more difficulty categorizing safety-related words after Black primes than after White primes. Moreover, we predicted that youth would sustain the perceived threat associated with Black men, which would result in comparable racial bias after child primes and after adult primes.”
