Answer:

Trend in ionic character of bonds: Cs-F > Si-C > Br-Cl > Cl-Cl    

                                                           (most)                          (least)                    

Explanation:

We know that, percentage ionic character of a bond is proportional to electronegativity difference between two constituting atoms.

                   Atom                                                  Electronegativity

                     Cs                                                              0.7

                      F                                                                4.0

                     Cl                                                                3.0

                     Br                                                               2.8

                      Si                                                                1.8

                     C                                                                 2.5

                Bond                                  Electronegativity difference

               Cs-F                                                                   3.3

               Cl-Cl                                                                   0.0

                Br-Cl                                                                  0.2

                Si-C                                                                    0.7

    So trend in ionic character of bonds:

     Cs-F > Si-C > Br-Cl > Cl-Cl

     (most)                         (least)

A mileage test is conducted for a new car model. Thirty randomly selected cars are driven for a month and the mileage is measure
Leni [432]

Answer:  (27.81,\ 29.39)

Explanation:

Given : Sample size : n= 30 , it means it is a large sample (n≥ 30), so we use z-test .

Significance level : \alpha: 1-0.95=0.05

Critical value: z_{\alpha/2}=1.96

Sample mean : \overline{x}=28.6

Standard deviation : \sigma=2.2

The formula to find the confidence interval is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

i.e. 28.6\pm (1.96)\dfrac{2.2}{\sqrt{30}}

i.e. 28.6\pm 0.787259889321

\approx28.6\pm 0.79=(28.6-0.79,28.6+0.79)=(27.81,\ 29.39)

Hence, the 95% confidence interval for the mean mpg in the entire population of that car model = (27.81,\ 29.39)
