- Surabaya city government survey to the public about the covid-19 situation. Condition society is categorized into 3: happy, ordinary and unhappy. From the sample of 1500 taken, 47% said they were happy. Give your feedback if the media online "X" states that the people of Surabaya are a bit happy. Use level significant 5% and calculate the P-value. (hint: the limit for little and for lots is 50%)Limits and Limit Laws 11One of the most important definitions in mathematics (calculus in particular) is that of the limit of a sequence. Consider the infinite sequence:1,1/2,1/3,1/4,.... Such a sequence can be represented as follows: an=1/n , n ∈ N Note that the elements of the sequence get arbitrarily close to 0 as n→∞. We call such a point the limit of the sequence. The formal definition for “L is the limit of a sequence an” is as follows: ∀∈ > 0, ∃N ∈ N, ∀ n ∈ N, n > N=⇒ |an−L| < ∈Negate this proposition to obtain the definition of “L is NOT the limit of a sequence an.”
- The Limit Comparison Test Question in PictureSixty-seven percent of the U.S households, or about 85 million families, own a pet, according to the 2019-2020 national pet owners survey conducted by the American pet products association (APPA). A small pet shop opens in your neighborhood and randomly and independently select 800 families to attend the grand opening of the store. Check the conditions of the central limit theorem for this scenario. What is the size of the population?A data set on monthly expenditures (rounded to the nearest dollar) incurred on fast food by a sample of 500 households has a minimum value of $5 and a maximum value of $147. Suppose we want to group these data into six classes of equal widths.a. Assuming we take the lower limit of the first class as $1 and the upper limit of the sixth class as $150, write the class limits for all six classes.b. Determine the class boundaries and class widths.c. Find the class midpoints.(For the first class set the upper limit of the previous class to be 0.)
