The value of <em>a</em> and <em>b</em> for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.
<h3>What is logarithmic regression?</h3>Logarithmic regression is a type of regression which is used to model the statement in which the growth or decay initially at rapid rate, and then slow down with respect to time.
The data of the table for the day and height of the stalk of corn is listed below.
Day (<em>x</em>) 9 12 22 40
Height (<em>y</em>) in 5 17 45 60
Mean of x values,
Mean of y values,
For the above table, the value of correlation coefficient is 0.99133. For these values, the logarithmic regression can be given as,
Compare it with the following logarithmic regression equation, we get
Hence, the value of <em>a</em> and <em>b</em> for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.

Answer: 0.283
Step-by-step explanation:
Formula to find the lower limit of the confidence interval for population proportion is given by :-
, where = sample proportion.
z* = Critical value
n= Sample size.
Let p be the true proportion of people who would purchase a defective item.
Given : Sample size = 993
Number of individuals would buy a slightly defective item if it cost less than a dollar = 305
Then, sample proportion of people who would purchase a defective item:
Critical value for 90% confidence interval = z*=1.645 (By z-table)
The lower bound of a 90% confidence interval for the true proportion of people who would purchase a defective item will become
[rounded to the nearest three decimal places.]
Hence, the lower bound of a 90% confidence interval for the true proportion of people who would purchase a defective item.= 0.283
