Step-by-step explanation:
n = 593
x = 28
Confidence level = 95%
So, at 95% = 1.96
Formula of confidence interval of one sample proportion:
=
=
=
Hence a 95 percent confidence interval for the proportion of all new websites that were anonymous is
b) May normality of p be assumed?
Condition for normality : np>10 and np(1-p)>10.
and
27.871 and 26.561063
Hence p is assumed to be normal since the condition is satisfied
35/100=0.35 and 42/0.35=120
so the answer is 120
Answer:
−7x−5y=4 - 7 x - 5 y = 4. Rewrite in slope-intercept form. Tap for more steps... The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is ...
Step-by-step explanation:
Answer: For altitudes up to 36,000 feet, the relationship between temperature and altitude can be described by the formula t=-0.0035a+g, where t is the temperature in degrees Fahrenheit, a is the altitude in feet, and g is the ground temperature in degrees Fahrenheit. Solve this formula for a.
