Apparently the questionnaire is incomplete, then the first part necessary to solve the question is left
The average daily volume of a computer stock in 2011 was
muμequals=35.135.1
million shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of
3030
trading days in 2014, he finds the sample mean to be
30.330.3
million shares, with a standard deviation of
sequals=12.612.6
million shares. Test the hypotheses by constructing a
9595%
confidence interval. Complete parts (a) through (c) below.
Answer: however, with the given options we can say that the correct option is "B", in which the value of the confidence interval is necessary to accept or reject the null hypothesis, we deduce that the value is not in the confidence interval so it must be rejected

Answer:
a) yes, as the number of seats (2352) is larger than the total audience (1912)
b) 440 empty seats
Step-by-step explanation:
a) total number of seats = number of rows x number of seats in each row
total number of seats = 49 x 48
total number of seats = 2352 seats
total audience = 1854 students + 58 teachers
total audience = 1912 people
b) empty seats = total number of seats - total audience
empty seats = 2352 - 1912
empty seats = 440
Answer:
Step-by-step explanation:
Part A
The units on 9500 must be miles. So if x is time, then 55 must be the rate at which she travels ie 55 miles per hour. So the answer must be A.
Part B
The trip began when the time was zero. Therefore x is zero. What remains is the mileage on the odometer when x = 0. The answer must be 1950.
