e 400 trials in which the assistant maintained a neutral expression, the driver stopped in 229 out of the 400 trials. Find a 95%
Fittoniya [83]

Answer:

Step-by-step explanation:

n = 400

Proportion p = 229/400= 0.5725

For 95% confidence interval we use Z value as 1.96

Std error = 0.025

margin of error = 1.96*0.025

Confidence interval 95% = 0.5725±Margin of error

= (0.524, 0.621)

b) When smiled x becomes 277

p = 0.6925

Std error = 0.023

Margin of error= 1.96*0.023

Confidence interval = (0.647, 0.738)

Smiling increases the chances of stopping since mean and conidence interval bounds are showing increasing trend.

PLEASE HELP ASAP!!!
Dimas [21]

Step-by-step explanation:

5x^2+2x=1

5x^2+2x-1=0

x=-b+/-√b^2-4ac÷2a

x=-2+/-√-2^2-(4×5×-1)÷2×5

x=-2+/+√4--20÷10

x=-2+/-√24÷10

x=-2+√24÷10 or -2-√24÷10

x=-2+4.9÷10 or -2-4.9÷10

x=2.9÷10 or -6.9÷10

x=0.29 or -0.69
