Answer:
There is convincing evidence that less than 40% of US households plan to purchase television in the next two years.
Null hypothesis H•= 40%
Alternative Hypothesis Hi < 40%
Step-by-step explanation:
Null hypothesis H•= 40%
From the survey, percentage of household that responded that they plan to buy new television in the next two years is given by
= 374/1010 × 100%

Therefore,
Alternative Hypothesis Hi<40%

Answer:
8.5 $
Step-by-step explanation:
Let Kiran 's salary is x $ per hour
hence cousin 's salary is x+ 30% of x per hour
or x+0.3x or 1.3x per hour
cousin 's earning 27(1.3x) = 35.1 x
kiran 's earning 23x
hence 35.1x +23x = 493.85
58.1x = 493.85
x = 493.85/ 58.1
x = 8.5 $
