The following data represent quantities of tea leaf pluckings (tender shoots from tea plants) from sixteen different plots of te

a bushes intended for experimental use in Ceylon, a type of tea from Sri Lanka. The tea bushes are randomly divided into four different treatment groups. Experimenters wish to determine if the mean number of pluckings differs among the four treatments. Test this using 5% significance, assuming that these samples are drawn from normal populations with equal variances. Treatment 1 Treatment 2 Treatment 3 Treatment Pluckings Pluckings Pluckings Pluckings 88 102 91 88 94 110 109 118 109 110 115 94 88 102 91 961. Give the null and alternative2. What is the value of the F-test statistic? Add the F-test statistic to the graph and shade the right tail. Use technology to determine the P-value for this hypothesis test. 3. What does the P-value tell you about the null and alternative hypotheses? 4. State a conclusion in the context of this problem.

Answer:

Explanation:

1)H_0 : All group means equal or \mu _1=\mu _2=\mu _3=\mu _4

H_1:\mu 1=\mu 2=\mu 3\neq \mu 4

At least one of the treatment group means are different

MSB = SSB / DFB = 71.16667

MSE = SSE / DFE = 109.375

F = MSB / MSE = 0.650667

3) P-value: 0.597576

The test statistic is not significant and failed to reject the null hypothesis.

4) The test statistic is not significant. So, there is no evidence to conclude that there is a difference between groups.

Lindsay​ Electronics, a small manufacturer of electronic research​ equipment, has approximately 6 comma 800 items in its invento
Nitella [24]

Answer:

99 items

Explanation:

Total number of items = 6,800

The number of items per type is:

A= 6,800*0.08\\A=544\ items\\B= 6,800*0.34\\B=2,312\ items\\C= 6,800*0.58\\C=3,944\ items

The number of items of each type counted per day is:

n_A=\frac{544}{20}\\n_A=27.2\\n_B=\frac{2312}{59}\\n_B=39.2\\n_C=\frac{3944}{121} \\n_C= 32.6\\

The total number of items counted per day is:

n = n_A+n_B+n_C=27.2+39.2+32.6\\n=99\ items\ per\ day

Consider the following data: currency (held outside banks) = $354 billion, checkable deposits = $250 billion, traveler's checks
Agata [3.3K]

Answer:

a). M1=$808 billion

b). M2=1,068 billion

Explanation:

M1 is the money supply that is the most liquid and is or can be easily converted into cash. The formula for calculating M1 is;

M1=C+D+T+S

where;

M1=money supply

C=currency held outside banks

D=checkable deposits

T=traveler's checks

S=small-denomination time deposits

In our case;

M1=unknown

C=$354 billion

D=$250 billion

T=$4 billion

S=$200 billion

replacing;

M1=(354+250+4+200)=$808 billion

M1=$808 billion

M2 includes elements of M1 and additional  money supply that are near liquid. The formula is;

M2=M1+savings deposit+mutual funds

where;

M1=$808 billion

savings=$100 billion

retail money market mutual funds=$160

replacing;

M2=(808+100+160)=1,068 billion

M2=1,068 billion

What makes the demand for u. s. dollars change? in world demand for u. s. exports ______ the demand for u. s. dollars. a in the
loris [4]

In the world demand for US, exports <u>increase</u> the demand for US dollars. a in the US interest rate differential <u>decreases</u> the demand for US dollars

An interest rate tells you how excessive the cost of borrowing is, or excessive the rewards are for saving. So, if you're a borrower, the interest charge is the quantity you're charged for borrowing cash, proven as a percentage of the total amount of the mortgage.

Traditionally, the guideline of thumb is that refinancing is a superb idea if you can reduce your interest rate by way of a minimum of 2%. but, many creditors say 1% financial savings is sufficient of an incentive to refinance.

As interest rates circulate up, the value of borrowing becomes more costly. because of this call, lower-yield bonds will drop, causing their price to drop. As interest prices fall, it will become less complicated to borrow money, and plenty of corporations will issue new bonds to finance growth.
