Refer to the accompanying data set and construct a % confidence interval estimate of the mean pulse rate of adult females; then do the same for adult males. Compare the results. Click the icon to view the pulse rates for adult females and adult males. Construct a % confidence interval of the mean pulse rate for adult females. nothing bpm nothing bpm (Round to one decimal place as needed.) Construct a % confidence interval of the mean pulse rate for adult males. nothing bpm nothing bpm (Round to one decimal place as needed.) Compare the results. A. The confidence intervals overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
B. The confidence intervals overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females.
C. The confidence intervals do not overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males.
D. The confidence intervals do not overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.

The 95% confidence interval of mean pulse rate for adult female is

The 95% confidence interval of mean pulse rate for adult male is  

The correct option is  C

Step-by-step explanation:

  Generally the sample mean for Male pulse rate is mathematically represented as

= >    

= >    

Generally the standard deviation for male pulse rate is mathematically represented as

=>  

=>  

From the question we are told the confidence level is  95% , hence the level of significance is    

=>  

Generally from the normal distribution table the critical value  of   is  

Generally the margin of error is mathematically represented as  

=>    

=>    

Generally 95% confidence interval is mathematically represented as  

=>    

=>    

  Generally the sample mean for Female pulse rate is mathematically represented as

= >    

= >    

Generally the standard deviation for Female  pulse rate is mathematically represented as

=>  

=>  

Generally from the normal distribution table the critical value  of   is  

Generally the margin of error is mathematically represented as  

=>    

=>    

Generally 95% confidence interval is mathematically represented as  

=>    

=>    

a negative exponent is translated as follows:

so, we have

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
