Answer:

600

Step-by-step explanation:

Given parameters:

    Number that rode in columns = 3\frac{2}{3} times the number that rode in rows.

       2200 rode in columns

Unknown:

Number of people that rode in rows = ?

Solution:

  Let the number of people that rode in columns  = C

   Let the number of people that rode in rows  = R

                 C = \frac{11}{3}R

Number of people that rode in rows  = 2200;

            2200 =  \frac{11}{3}R

             11R  = 2200 x 3

                R  = \frac{2200 x 3}{11}

                R = 200 x 3

               R  = 600

Number of people that rode in rows  = 600

4b) Work out the mean and standard deviation of the following: picture included
Jlenok [28]

Answer:

Yes, your simultaneous equations are correct;

Solve them like so:

170 + 1.6449σ = 180 - 0.8416

2.4865σ = 10

σ = 4.0217...

μ = 170 + 1.6449(4.0217...)

μ = 176.615...

MS is correct, you must've made an error in solving or rearranging

A confidence interval for the population mean μ tells us which values of μ are plausible (those inside the interval) and which v
solmaris [256]

Answer:

90% confidence interval for the mean blood pressure of all executives is 123.12 to 129.02.

The closest option is A

Step-by-step explanation:

Confidence Interval = mean + or - Error margin (E)

mean = 126.07

sd = 15

n = 72

degree of freedom = n - 1 = 72 - 1 = 71

Confidence level (C) = 90% = 0.9

Significance level = 1 - C = 1 - 0.9 = 0.1 = 10%

t-value corresponding to 71 degrees of freedom and 10% significance level is 1.6667

E = t×sd/√n = 1.6667×15/√72 = 2.95

Lower limit = mean - E = 126.07 - 2.95 = 123.12

Upper limit = mean + E = 126.07 + 2.95 = 129.02

90% confidence interval for the mean blood pressure of all executives is between a lower limit of 123.12 and an upper limit of 129.02.
